FV102 Striker was the Swingfire wire-guided anti-tank missile carrying member of the CVR(T) family. The FV102 Striker was externally very similar to the FV103 Spartan but carried five missiles in a ready-to-fire bin at the back of the vehicle. Five reload missiles were carried in
252-456: A 3-inch anti-aircraft gun . Although a number were ordered and fifty delivered in 1942, they were not put into service as the immediate threat passed. The design was rejected in favor of developing a 17 pounder armed Cromwell tank variant, ultimately leading to the Comet tank . The Tortoise "heavy assault tank", intended for use in breaking through fixed defensive lines, was well armoured and had
378-577: A 90 mm gun. As Soviet designs became more heavily armoured, the 90 mm gun became ineffective and the Kanonenjagdpanzers were retrofitted for different roles or retired. Some provisions were made for the fitting of a 105 mm cannon, and many of the vehicles were modified to fire HOT or TOW missiles in place of a main gun. These upgraded variants remained in service into the 1990s. With the development of flexible anti-tank missiles , which were capable of installation on almost any vehicle in

The vehicles are designed specifically to engage and destroy enemy tanks , often with limited operational capacities. While tanks are designed for front-line combat, combining operational mobility and tactical offensive and defensive capabilities and performing all primary tasks of

While allegedly limited and low-intensity in that the territories occupied in force by central government forces are returned (as they cannot be held permanently as yet) at the end of the offensives (with the stated, but sometimes unstated, purpose of weakening the opposition and independence movements), human rights organizations and national governments outside of Burma question

The most famous Italian tank destroyer of the Second World War was a self-propelled gun. The Semovente da 75/18 , based on the M13/40 frame, was developed to support front-line infantry, and therefore had fixed armament: a 75 mm gun in casemate. However, thanks to its low height (185 cm) and
882-408: A colonial presence above what the foreign power may wish to bear. Against a local regime, guerrillas may make governance impossible by terror strikes and sabotage or even a combination of forces to depose their local enemies in conventional battle. Those tactics are useful in demoralizing an enemy and raising the morale of the guerrillas. In many cases, guerrilla tactics allow a small force to hold off
1008-433: A comparatively short-barreled high-velocity anti-tank gun, usually with a muzzle brake , enabling it to function as a tank destroyer. The Sturmgeschütz III from its 1938 origin used a new casemate-style superstructure with an integrated design, similar to the later Jagdpanzer vehicle designs' superstructure, to completely enclose the crew. It was employed in infantry support and offensive armoured operations as well as in
1134-432: A confined local area or country, however, is not always strictly necessary. Guerrilla and revolutionary groups can still operate by using the protection of a friendly regime, drawing supplies, weapons, intelligence, local security, and diplomatic cover. The Al Qaeda organization is an example of the latter type, drawing sympathizers and support primarily from the wide-ranging Muslim world, even after American attacks eliminated

In most cases, there is a leadership aiming for a clear political objective. The organization is typically structured into political and military wings, sometimes allowing the political leadership plausible deniability of military attacks. The most fully elaborated guerrilla warfare structure

Flanking fire by TDs was emphasized, both to penetrate thinner enemy side armour, and to reduce the likelihood of accurate enemy return fire. All American tank destroyers were officially known by exactly the same collective term used for American self-propelled artillery ordnance, "gun motor carriage". The designs were intended to be very mobile and heavily armed. Most of

Other French tank destroyers were being developed, including the SOMUA SAu-40, ARL V39 and various ad hoc conversions of the Lorraine 37L . In the face of the Warsaw Pact, a general need for extra firepower was identified. In the late 1960s, West Germany developed the Kanonenjagdpanzer , essentially a modernized World War II Jagdpanzer mounting

The lack of a turret increased the vehicle's internal volume, allowing for increased ammunition stowage and crew comfort. Eliminating the turret let the vehicle carry thicker armour, and also let this armour be concentrated in the hull. Sometimes there was no armoured roof (only a weather cover) to keep the overall weight down to

Guerrilla tactics and strategy are summarized below and are discussed extensively in standard reference works such as Mao 's On Guerrilla Warfare . Mao's theory of people's war divides warfare into three phases. In the first phase,
1890-399: A much slower process than simply rotating a powered turret. If the vehicle became immobilized due to engine failure or track damage, it could not rotate its gun to counter opposing tanks, making it highly vulnerable to counterfire. This vulnerability was later exploited by opposing tank forces. Even the largest and most powerful of German tank destroyers were found abandoned on the field after
2016-523: A simple national liberation claim untenable. Whatever the exact mix of persuasion or coercion used by guerrillas, relationships with civil populations are one of the most important factors in their success or failure. Terror is used to focus international attention on the guerrilla cause, liquidate opposition leaders, extort cash from targets, intimidate the general population, create economic losses, and keep followers and potential defectors in line. The widespread use of terror by guerrillas and their opponents
2142-721: A somewhat extemporized nature. Mounting the gun on the Valentine tank chassis in a fixed superstructure gave the Archer , looking somewhat like the light-chassis German Marder III in appearance. The 17 pounder was also used to re-equip the US-supplied M10 tank destroyer , replacing the American 3-inch gun to produce the 17pdr SP Achilles . In 1942 the General Staff agreed on investigating self-propelled mountings of
2268-428: A tank destroyer was used against enemy tanks from a defensive position such as by ambush, the lack of a rotating turret was not particularly critical, while the lower silhouette was highly desirable. The turretless design allowed accommodation of a more powerful gun, typically a dedicated anti-tank gun (in lieu of a regular tank's general-purpose main gun that fired both anti-tank and high explosive ammunition) that had

For instance, 202 obsolete Panzer I light tanks were modified by removing the turret and were rebuilt as the Panzerjäger I self-propelled 4.7 cm PaK(t) . Similarly, Panzer II tanks were used on the eastern front. Captured Soviet 76.2 mm anti-tank guns were mounted on modified Panzer II chassis, producing the Marder II self-propelled anti-tank gun. The most common mounting
2520-635: A very powerful 32-pounder (94 mm) gun, but did not reach service use. By 1944, a number of the Shermans in British use were being converted to Sherman Fireflies by adding the QF 17 pounder gun. Initially this gave each troop (platoon) of Shermans one powerfully armed tank. By war's end—through the production of more Fireflies and the replacement of Shermans by British tanks—about 50% of Shermans in British service were Fireflies. The Sherman Firefly, however,
2646-523: Is a common feature of modern guerrilla conflicts, with civilians attempting to mollify both sides. At times, a civil population may be the main targets of guerrilla attacks, as in Palestinian operations against Israeli civilians. Such tactics may backfire and cause the civil population to withdraw its support or to back countervailing forces against the guerrillas. Guerrillas must plan carefully for withdrawal once an operation has been completed or if it

If working clandestinely, guerrilla operatives may disguise their membership in the insurgent operation and use deception to ferret out needed data. Employment or enrollment as a student may be undertaken near the target zone, community organizations may be infiltrated, and even romantic relationships struck up in intelligence gathering. Public sources of information are also invaluable to

The withdrawal phase is sometimes regarded as the most important part of a planned action, as getting entangled in a lengthy struggle with superior forces is usually fatal to insurgent, terrorist or revolutionary operatives. Withdrawal is usually accomplished using a variety of different routes and methods and may include quickly the scouring of the area for loose weapons, the cleaning-up of evidence, and

In the early stages of the Vietnam War, American officials "discovered that several thousand supposedly government-controlled 'fortified hamlets' were in fact controlled by Viet Cong guerrillas, who 'often used them for supply and rest havens.'" Popular mass support in

Mobility and speed are the keys; wherever possible, the guerrilla must live off the land or draw support from the civil population in which it is embedded. In that sense, "the people" become the guerrilla's supply base. The financing of terrorist or guerrilla activities ranges from direct individual contributions (voluntary or non-voluntary) to

This opponent may be state sponsored, or private non-state actors driven by religious or other ideology in urban, semi-urban and rural areas. Modern guerrilla warfare at its fullest elaboration is an integrated process, complete with sophisticated doctrine , organization, specialist skills and propaganda capabilities. Guerrillas can operate as small, scattered bands of raiders, but they can also work side by side with regular forces or combine for far-ranging mobile operations in squad , platoon or battalion sizes or even form conventional units. Based on their level of sophistication and organization, they can shift between all those modes as

Numerous other regimes, however, give such considerations short shrift, and their counterguerrilla operations have involved mass murder, genocide, starvation as well as
5922-521: The 1960s, the concept of the tank destroyer has morphed into light vehicles with missiles. With the weight of main battle tanks growing to the forty to seventy-tonne range, airborne forces were unable to deploy reasonable anti-tank forces. The result was a number of attempts to make a light vehicle, including the conventional ASU-85 , M56 Scorpion , the recoilless rifle-armed Ontos , and missile-armed Humber Hornet armoured truck and Sheridan light assault vehicle. The recent entries into that category are
6048-460: The 37 mm gun was ineffective against most enemy tanks by the time it entered service. By far the most common US design, and the first that was fully tracked and turreted (which became the American hallmark of World War II "tank destroyer" design) was the 3-inch gun motor carriage M10 , later supplemented by the 90 mm gun motor carriage M36 —both based on the M4 Sherman hull and powertrain—and
6174-467: The 57 mm Ordnance QF 6 pounder when that became available. There was extra impetus given to the development of anti-tank weaponry, which culminated in the 76mm Ordnance QF 17 pounder , widely considered one of the best anti-tank guns of the war. Towed anti-tank guns were the domain of the Royal Artillery and vehicles adapted to mount artillery, including anti-tank self-propelled guns such as

The Soviets produced high numbers of the 85 mm SU-85 and 100 mm SU-100 self-propelled guns based on the same chassis as the T-34 medium tank; the heavier-duty powertrain and hull of the IS-2 heavy tank were instead used to produce

Most of the Ho-Ni units were retained within the Japanese home islands to form part of the defenses against the projected American invasion , and did not see combat before the surrender of Japan . The Type 2 Ho-I Gun tank used the Type 1 Chi-He medium tank chassis. It was designed as a self-propelled howitzer , mounting a short barreled Type 99 75 mm gun to provide close-in fire support. For deployment,
6678-560: The ISU-152. The ISU-152 built as a heavy assault gun, relied on the weight of the shell fired from its M-1937/43 howitzer to defeat tanks. In 1943, the Soviets also shifted all production of light tanks like the T-70 to much simpler and better-armed SU-76 self-propelled guns, which used the same drive train. The SU-76 was originally designed as an anti-tank vehicle, but was soon relegated to
6804-528: The Romanian Army leadership sought for ways to improve its anti-tank capabilities. The initial plan was the creation of a tank comparable in characteristics to the T-34 ; instead, Romania went for a number of tank destroyers, since they were more adequate for its industry. The Mareșal is probably the best known Romanian AFV from the war; historians Steven Zaloga and Mark Axworthy state that it inspired

British tanks in the early years of the war, both infantry tanks and cruiser tanks , were (with the exception of the pre-war Matilda I design) equipped with a gun capable of use against contemporary enemy tanks—the 40 mm Ordnance QF 2 pounder . This was replaced with
9324-434: The design of the later German Hetzer . Standing at only around 1.5 m tall, which would have made it very difficult to hit for its enemies, the Mareșal was a lightly armored, but highly mobile vehicle. It was armed with the Romanian 75 mm Reșița M1943 anti-tank gun, which proved to be among the best of its class during World War II, according to Mark Axworthy. During tests, the Mareșal proved to be superior in many aspects to
9450-425: The disguising as peaceful civilians. In the case of suicide operations, withdrawal considerations by successful attackers are moot, but such activity as eliminating traces of evidence and hiding materials and supplies must still be done. Guerrillas typically operate with a smaller logistical footprint than to conventional formations, but their logistical activities can be elaborately organized. A primary consideration
9576-470: The first two decades of the 21st century has seen the emergence of gun-armed wheeled vehicles, sometimes called "protected gun systems", which may bear a superficial resemblance to tank destroyers, but are employed as direct fire support units typically providing support in low-intensity operations , as was done in wars in Iraq and Afghanistan . Dedicated anti-tank vehicles made their first major appearance in
9702-489: The growth of freedom , democratic institutions, and free market economies. ... US policy recognizes that indirect, rather than direct, applications of US military power are the most appropriate and cost-effective ways to achieve national goals in a LIC environment. The principal US military instrument in LIC is security assistance in the form of training, equipment, services and combat support. When LIC threatens friends and allies,
9828-601: The guerrilla cause to international attention, putting pressure on local opponents to make concessions or garnering sympathetic support and material assistance. Foreign sanctuaries can add heavily to guerrilla chances, furnishing weapons, supplies, materials, and training bases. Such shelter can benefit from international law, particularly if the sponsoring regime is successful in concealing its support and in claiming plausible deniability for attacks that are by operatives based in its territory. The VC and NVA made extensive use of such international sanctuaries during their conflict, and
9954-447: The guerrilla force can constantly keep pressure on its foes and diminish its numbers and still allow escape with relatively few casualties. The intention of such attacks is only military but also political in aiming to demoralize target populations or governments or by goading an overreaction that forces the population to take sides for or against the guerrillas. Examples range from chopping off limbs in various internal African rebellions to
10080-525: The guerrilla, from the flight schedules of targeted airlines, to public announcements of visiting foreign dignitaries, to US Army Field Manuals. Modern computer access via the World Wide Web makes harvesting and collation of such data relatively easy. The use of on the spot reconnaissance is integral to operational planning. Operatives will "case" or analyze a location or potential target in depth- cataloging routes of entry and exit, building structures,
10206-540: The guerrillas gain the support of the population by attacking the machinery of government and distributing propaganda . In the second phase, escalating attacks are made on the government's military and vital institutions. In the third phase, conventional fighting is used to seize cities, overthrow the government, and take control of the country. Mao's seminal work On Guerrilla Warfare , has been widely distributed and applied, nowhere more successfully than in Vietnam, under
10332-482: The gun tank was intended to be used in a fire support company for each of the tank regiments. No Type 2 Ho-I gun tanks are known to have engaged in combat prior to Japan's surrender. The prototype was built in 1942 and 31 units were produced in 1944. The Type 4 Ho-Ro self-propelled artillery used a modified Type 97 chassis. On to this platform, a Type 38 150 mm howitzer was mounted. The main gun could fire Type 88 APHE rounds and HEAT rounds. Given its breech loader,
10458-607: The heavier-hitting 122 mm -armed ISU-122 and 152 mm -armed ISU-152 , both of which had impressive anti-tank capabilities earning each of them the Russian nickname Zveroboy ("beast killer") for their ability to destroy German Tigers , Panthers and Elefants . The predecessor of the ISU 152 was the SU-152 , built on the KV-1s chassis and shared many similarities (including its gun) with
10584-406: The infantry-support role. U.S. Army and counterpart British designs were very different in conception. U.S. doctrine was based, in light of the fall of France , on the perceived need to defeat German blitzkrieg tactics, and U.S. units expected to face large numbers of German tanks, attacking on relatively narrow fronts. These were expected to break through a thin screen of anti-tank guns, hence
10710-453: The inherent right of states to use force in individual or collective self-defense against armed attack. Boaz Ganor notes that scholars once labeled terrorism as "low-intensity warfare." However, this terminology has become obsolete due to the intricate nature of multidimensional warfare and the mass impact of contemporary terrorist attacks, such as the September 11 attacks . As the name suggests, in comparison with conventional operations
10836-505: The limit that the chassis could bear. The absence of a turret meant that tank destroyers could be manufactured significantly cheaper, faster, and more easily than the tanks on which they were based, and they found particular favor when production resources were lacking. The first German tank destroyers were the Panzerjäger ("Tank Hunters"), which mounted an existing anti-tank gun on a convenient chassis for mobility, usually with just
10962-431: The location of phones and communication lines, the presence of security personnel, and a myriad of other factors. Finally, intelligence is concerned with political factors such as the occurrence of an election or the impact of the potential operation on civilian and enemy morale. Relationships with civil populations are influenced by whether the guerrillas operate among a hostile or friendly population. A friendly population
11088-454: The maximum rate of fire was only 5 rounds per minute. The gun's elevation was restricted to 30 degrees by the construction of the chassis. Other design issues included the fact that although the gun crew was protected by a gun shield with armour thickness of 25 mm at the front, the shield only extended a very short distance on the sides; leaving the rest of the sides and back exposed. They were rushed into service, deployed and saw combat during
11214-453: The military leader and theorist Võ Nguyên Giáp . Giap's People's War, People's Army closely followed the Maoist three-stage approach but with greater emphasis on flexible shifting between mobile and guerrilla warfare, and opportunities for a spontaneous "general uprising" of the masses, in conjunction with guerrilla forces. Guerrilla organization can range from small local rebel groups with
11340-492: The modern battlefield. But there are still dedicated anti-tank vehicles with very heavy long-range missiles, and ones intended for airborne use. There have also been dedicated anti-tank vehicles built on ordinary armoured personnel carrier or armored car chassis. Examples include the U.S. M901 ITV (Improved TOW Vehicle) and the Norwegian NM142 , both on an M113 chassis, several Soviet ATGM launchers based on
11466-593: The more successful German tank destroyers was designed as a self-propelled artillery gun, the Sturmgeschütz III . Based on the Panzer III tank chassis, the Sturmgeschütz III was originally fitted with a short barreled low-velocity howitzer-like gun, and was assigned to the artillery arm for infantry fire support as an assault gun . Later, after encountering Soviet tanks, it was refitted with
11592-402: The mountains and jungles, blend into the population and also depend on a support base among the people. Rooting guerrillas out of both types of areas can be difficult. Foreign support in the form of soldiers, weapons, sanctuary, or statements of sympathy for guerrillas is not strictly necessary, but it can greatly increase the chances of an insurgent victory. Foreign diplomatic support may bring
11718-496: The number of German tanks encountered by American forces steadily decreased throughout the war, most battalions were split up and assigned to infantry units as supporting arms, fighting as assault guns or being used essentially as tanks. In this sense they were an alternative to the Independent tank battalions that were attached to various Infantry Divisions. The expectation that German tanks would be engaged in mass formation
11844-479: The opposing parties operate along such lines. Low-intensity conflict is defined by the United States Army as: ... a political-military confrontation between contending states or groups below conventional war and above the routine, peaceful competition among states. It frequently involves protracted struggles of competing principles and ideologies. Low-intensity conflict ranges from subversion to
11970-504: The proliferation of ATGMs, some gun-armed tank destroyers remain in use. China has developed the tracked PTZ89 and the wheeled PTL02 tank destroyers. The PTZ89 is armed with a 120 mm smoothbore cannon while the PTL02, developed by NORINCO for the PLA's new light (rapid reaction) mechanized infantry divisions, carries a 100 millimeters (3.9 in) one (a version armed with a 105 mm rifled gun
12096-424: The reconnaissance units. There were also 37 mm armed TKS-D (2 experimental vehicles) and 47 mm armed TKD (4 experimental vehicles). It is not certain whether they were used operationally at all. Due to the quick defeat of France, few French vehicles were built. The Laffly W15 TCC ( Chasseur de chars ) was an attempt to quickly build a light tank destroyer by mounting a 47 mm SA37 anti-tank gun onto
12222-583: The same chassis: Marder was straightforwardly an anti-tank gun on tracks whereas the Jagdpanzer 38 traded some firepower (its 7.5 cm Pak 39 , designed to operate within the confines of a fully armoured fighting compartment, fires the same projectiles from a reduced propellant charge compared to Marder's 7.5 cm Pak 40 ) for better armour protection and ease of concealment on the battlefield. Except for most American designs, all tank destroyers were turretless vehicles with fixed or casemate superstructures. When
12348-476: The semi-automatic command to line of sight ( SACLOS ) system where the controller merely sights the target. Secondary armament was a general purpose machine gun . The Striker was developed for the British Army to fire the Swingfire missile. The first production vehicles were delivered in 1975 and used in British Army service by the Royal Artillery anti-tank guided missile batteries. The vehicle initially
12474-451: The side armor with re-positioned observation visors. Production began in 1943, with only 54 completed. The other variant produced was the Type 3 Ho-Ni III , which mounted a Type 3 75 mm tank gun in a completely enclosed armored casemate to address the issue of crew protection in close combat. The welded superstructure had sloped armour and the gun mount had additional stamped armour plate. The total number produced of all three types in
12600-528: The situation changes. Careful rehearsals and "dry runs" are usually conducted to work out problems and details. Many guerrilla strikes are not undertaken unless clear numerical superiority can be achieved in the target area, a pattern typical of VC/NVA and other "people's war" operations. Individual suicide bomb attacks offer another pattern, typically involving only the individual bomber and his support team, but they too are spread or metered out based on prevailing capabilities and political winds. Whatever approach
12726-473: The situation demands, as guerrilla warfare is flexible, not static. Guerrilla tactics are based on intelligence , ambush , deception , sabotage , and espionage , undermining an authority by long, low-intensity confrontation. It can be quite successful against an unpopular foreign or local regime, as demonstrated by the Vietnam War . A guerrilla army may increase the cost of maintaining an occupation or
12852-416: The suicide bombings of Palestine and Sri Lanka to sophisticated maneuvers by Viet Cong and NVA forces against military bases and formations. For successful operations, surprise must be achieved by guerrillas. If the operation has been betrayed or compromised, it is usually called off immediately. Intelligence is also extremely important, and detailed knowledge of the target's dispositions, weaponry, and morale
12978-416: The tank-hull based designs used special open-topped turrets of a differing design from the original tank it was based on, which was meant to both save weight and to accommodate a larger gun. The earliest expedient design was mounting a 75 mm M1897 field gun in a limited-traverse mount on an M3 half-track , which was designated 75 mm gun motor carriage M3 . Another, considerably less successful, early design
13104-441: The time was spent in training, intelligence gathering, political and civic infiltration, propaganda indoctrination, construction of fortifications, or foraging for supplies and food. The large numbers of such groups striking at different times, however, gave the war its "around-the-clock" quality. The low-intensity fighter or guerrilla can be difficult to beat, but certain principles of counter-insurgency warfare are well known since
13230-402: The tough VC/NVA fortified base camps and tunnel complexes encountered by US forces during the Vietnam War. Their importance can be seen by the hard fighting sometimes engaged in by communist forces to protect those sites. However, when it became clear that defense was untenable, communist units typically withdrew without sentiment. Guerrilla warfare is often associated with a rural setting, which
13356-564: The umbrella of a friendly Taliban regime in Afghanistan. An apathetic or hostile population makes life difficult for guerrillas, and strenuous attempts are usually made to gain their support. They may involve not only persuasion but also a calculated policy of intimidation. Guerrilla forces may characterize a variety of operations as a liberation struggle, but that may or may not result in sufficient support from affected civilians. Other factors, including ethnic and religious hatreds, can make
13482-564: The unwieldy Elefant , now fitted to the chassis of the medium Panther tank , providing greatly improved armour-penetrating capability in a medium-weight vehicle. Facing an increasingly defensive war, the German Army turned to larger and more powerfully armed Jagdpanzer designs, and in July 1944 the first Jagdtiger rolled off the production line; it was the heaviest German armoured fighting vehicle to go into active service. The Jagdtiger
13608-473: The use of the armed forces . It is waged by a combination of means, employing political, economic, informational, and military instruments. Low-intensity conflicts are often localized, generally in the Third World , but contain regional and global security implications. The manual also says: ... successful LIC operations, consistent with US interests and laws , can advance US international goals such as
13734-405: The vehicle was originally designed as a very heavily armoured self-propelled assault gun to breach Germany's Siegfried Line defenses. Of these tank destroyers, only the 90 mm gun of the M36 proved effective against the frontal armour of Germans' larger armored vehicles at long range. The open top and light armour made these tank destroyers vulnerable to anything greater than small-arms fire. As
13860-413: The vehicle. The bin was elevated to 35° (622mils) for firing. The targeting sight could be demounted and operated at a distance from the vehicle which could remain in cover, even completely screened as the missile can turn up to 90° after launch to come onto the target heading. The missiles were originally steered by joystick control using manual command to line of sight ( MCLOS ). This was later updated to
13986-508: The veracity of, and sometimes outright refute, these claims. The governments of Sudan have also engaged in limited military offensives (analogous to Burma's "annual dry season offensives") against various armed opposition and independence movements, which have often escalated into full-scale warfare, particularly in the south and Darfur , but also until recently in the east . These military actions ( First Sudanese Civil War and Second Sudanese Civil War ) have, over time, continued to ravage
14112-508: The war. In Poland there was also a secret order and many non-military resistance organizations like " Zegota " which helped thousands of Jews save their lives. When the Red Army entered Poland in 1944, the Poles wanted to support them in the fight against the Germans, but the Soviets betrayed them, even though during Operation Tempest , the partisans significantly accelerated the Russian attack,
14238-557: The wider Catholic community in what they described as retaliation. At times, there were bouts of sectarian tit-for-tat violence, as well as feuds within and between paramilitary groups. The British security forces undertook policing and counter-insurgency, primarily against suspected republicans. This included the internment without trial of anyone accused of being, or supporting, Republicans. Investigations also revealed significant collusion between British state forces and loyalist paramilitaries, and furthermore loyalist paramilitaries such as
14364-576: Was a German 75 mm anti-tank gun on the Czech Panzer 38(t) chassis as the Marder III . The Panzer 38(t) chassis was also used to make the Jagdpanzer 38 casemate style tank destroyer. The Panzerjäger series continued up to the 88 mm equipped Nashorn . German tank destroyers based on the Panzer III medium tank and later German tanks had more armour than their tank counterparts. One of
14490-450: Was a failed assumption. In reality, German attacks effectively used combined arms on the ground, fighting cohesively. American tank destroyer battalions comprised three tank destroyer companies supported by nine security sections. The single-purpose tactics of the tank destroyer battalion failed to account for non-tank threats. In the 1950s the goal of providing airborne forces with a parachute-capable self-propelled anti-tank weapon led to
14616-528: Was a sectarian and ethno-nationalistic conflict, fuelled by historical events and longstanding oppression by the UK's military and security services. By the mid-1960s, the Northern Ireland civil rights movement began organizing Irish Catholics to protest, among other factors, disenfranchisement, abuses of power such as discrimination in the housing and job markets perpetuated by the ruling governments in
14742-525: Was based on the Tiger II heavy tank featured a very large 128 mm PaK 44 cannon and heavy armour protection. Only 88 Jagdtiger vehicles were produced, barely matching the total number of the earlier Ferdinand / Elefant vehicles. They were first deployed to combat units in September 1944. The decision of German armoured vehicle designers to use a casemate-style superstructure for all tank destroyers had
14868-529: Was delayed until post war before entering service. A cut-down 17 pdr, the 77mmHV was used to equip the Comet tank in the last year of the war. The closest the British came to developing an armoured tank destroyer in the vein of the German Jagdpanzers or Soviet ISU series was the Churchill 3-inch gun carrier—a Churchill tank chassis with a boxy superstructure in place of the turret and mounting
14994-540: Was indeed the case with the definitive operations of Mao and Giap, and the mujahadeen of Afghanistan . Guerrillas, however, have successfully operated in urban settings, such as in Argentina and Cyprus. In both cases, guerrillas rely on a friendly population to provide supplies and intelligence. Rural guerrillas prefer to operate in regions providing plenty of cover and concealment, especially heavily forested and mountainous areas. Urban guerrillas, rather than melting into
15120-546: Was mechanically unreliable and difficult to maneuver, and once all ninety-one unturreted "Porsche Tiger" hulls/drive systems were converted, no more were built. The German Army had more success with the Jagdpanther . Introduced in mid-1944, the Jagdpanther, of which some 415 examples were produced, was considered the best of the casemate-design Jagdpanzer designs. It featured the same powerful PaK 43 88 mm cannon used on
15246-670: Was powered by the Jaguar J60 4.2-litre 6-cylinder petrol engine - the same as used by several Jaguar cars. This was then replaced by a Cummins BTA 5.9 diesel engine , as used in British Army FV107 Scimitars , under the CVR(T) life extension programme. The Striker entered service in 1976 with the Royal Artillery of the BAOR , but then was transferred to the Royal Armoured Corps where they served in formation reconnaissance regiments . On 24 March 2003, during
15372-608: Was seen by the Chinese and Vietnamese communists during the revolutionary wars of East and Southeast Asia. A simplified example of this more sophisticated organizational type, which was used by revolutionary forces during the Vietnam War, is shown below. Guerrilla operations typically include a variety of attacks on transportation routes, individual groups of police or military, installations and structures, economic enterprises, and targeted civilians. Attacking in small groups and using camouflage and often captured weapons of that enemy,
15498-687: Was the M6 gun motor carriage which mounted the US 37 mm anti-tank gun facing to the rear on the bed of a Dodge 3/4-ton light truck. The M3 was first used against the Japanese in the Philippines and then in the Tunisian campaign of the war in North Africa. Some were supplied to British units who used them within armoured car reconnaissance regiments for fire support. The M6 GMC was unarmoured and
15624-478: Was the first self-propelled gun design of the Imperial Japanese Army . They were meant to be self-propelled artillery and tank destroyers for armoured divisions . The plan was for the Type 1 Ho-Ni I gun tank to form part of a fire support company in each of the tank regiments. The Type 1 Ho-Ni I was developed by using the existing Type 97 Chi-Ha medium tank chassis and engine, and replacing
15750-524: Was the status of Northern Ireland. Unionists and loyalists, who descended from colonists who arrived during the Ulster Plantation , displacing all but a handful of native clans and farmers, were Ulster Protestants and wanted Northern Ireland to remain within the United Kingdom. Irish nationalists and republicans, who were mostly Irish Catholics, wanted to end the Partition of Ireland , leave
15876-539: Was usable against both tanks and in supporting infantry, there was a need to put the 17 pdr into a tank for use against the enemy's heavy tanks. The Cruiser Mk VIII Challenger was a project to bring a 17 pdr tank into use to support the Cromwell cruiser tank . Delays led to it being outnumbered in use by the Sherman Firefly —but a derivative of Challenger was the more or less open-topped variant Avenger , which
