On 24 June 2024, Al-Qassam Brigades published footage of its forces attacking an M113 using a Chinese HJ-8 ATGM, hitting the vehicle, caused an external fire on the carry-on CARPET demining system. Several disabled Zelda APCs in Nabatieh , Lebanon and Gaza have revealed VBIED use by the IDF, where the vehicles are filled with explosives, towed to their target, and detonated. An unknown number of M113s were converted into Unmanned Ground Vehicles and were observed to be acting as VBIEDs in Rafah. In November 2024 IAI showed videos of unmanned M113 units working with unmanned D9 bulldozers in what appeared to be Gaza as an example of its new teaming system for robotic units. The Israel Defense Forces still operates large numbers of

420-607: A dismounted infantry unit. The remaining SPATS platoon was reequipped with M113s in late 1966 and the mortar platoon was deactivated in early 1967. From early 1967, D/16th had three line platoons equipped with M113s and eventually, its diesel version, the M113A1. It was also standardized in late 1968 with three machine guns per track, one M2 .50 caliber and two M60 machine guns mounted on each side. The M113s were instrumental in conducting reconnaissance in force (RIFs), search and destroy missions, and large invasions (incursions) such as

490-464: A front-mounted trim vane; they are propelled in the water by their tracks. The Vietnam War was the first combat opportunity for mechanized infantry , a technically new type of infantry with its roots in the armored infantry of World War II , now using the M113 armored personnel carrier. In addition, armored cavalry squadrons in Vietnam consisted largely of M113s, after replacing the intended M114 in

560-702: A modernized version known as an "MRV" (medium reconnaissance vehicle). The MRV featured a Scorpion turret with 76 mm gun, improved fire control, and passive night vision equipment. Regiments using the M113 included former Citizens' Military Forces (CMF) units like the 4/19th Prince of Wales Light Horse Regiment (armoured reconnaissance) and Regular units such as 2ns Cavalry Regiment (armoured reconnaissance) and 3/4th Cavalry Regiment (APC Regiment). An Armoured Reconnaissance Troop consisted of Alpha Track – Charlie Track (M113 LRV) Bravo – Delta Track (M113 MRV) Echo Track (M113 APC) with Assault Section (armoured infantry) later known as Scouts... The Israel Defense Forces are

630-423: A partnership with Sumitomo Heavy Industries forming Link-Belt. FMC totally exited the partnership in 1998. FMC Technologies was an American company that produced equipment for exploration and production of hydrocarbons. FMC Technologies was incorporated in 2000 when FMC Corporation divested its machinery businesses. It exists today as a part of TechnipFMC , after a merger with Technip in 2017. JBT Corporation

In 1946, FMC bought Bolens Lawn and Garden Equipment . FMC changed its name again in 1948, becoming F ood M achinery and C hemical Corporation. In 1961 the name was changed to FMC Corporation. In 1967,

770-637: A true infantry fighting vehicle rather than an armored personnel carrier. Pacific Car and Foundry entered the steel-armored XM701, but this proved to be too slow and too heavy to be airmobile, even in the C-141. FMC entered the XM734, which was largely the ACAV M113, but whereas the M113 seated the troops facing inward on benches along the walls, the XM734 sat them facing outwards on a central bench. Four gun ports and vision blocks were added on each side to allow

840-680: A variety of roles, and armor battalions contained M113s within their headquarters companies, such as the maintenance section, medical section, vehicle recovery section, mortar section, and the scout (reconnaissance) section. United States Army mechanized infantry units in Vietnam were fully equipped with the M113 APC/ACAV, which consisted of one headquarters company and three line companies, normally with an authorized strength of approximately 900 men. Ten U.S. mechanized infantry battalions were deployed to Vietnam from 1965 until their departure in 1972. Company D, 16th Armor, 173rd Airborne Brigade ,

910-561: A vehicle that provided the protection of the M75 and the low weight and mobility of the M59. FMC responded with two proposals; two versions of the aluminum T113 – a thickly and a more thinly-armored one, along with the similar but mostly steel T117. The thickly-armored version of the T113 – effectively the prototype of the M113 – was chosen because it weighed less than its steel competitor, whilst offering

980-471: Is Spanish for Armored Tracked Carrier. In the Ukrainian Army it is called "Emka" (M). The basic M113 armored personnel carrier can be fitted with a number of weapon systems. The most common weapon fit is a single .50 caliber M2 machine gun. However, the mount can also be fitted with a 40 mm Mk 19 automatic grenade launcher. A number of anti-tank weapons could be fitted to the standard variant:

1050-584: Is an American food processing machinery and airport equipment company. JBT Corporation was incorporated in 2008 when FMC Technologies divested its non-energy businesses. FMC Corporation operated a phosphate mine and plant in Idaho on the Fort Hall Indian Reservation of the federally recognized Shoshone-Bannock Tribes. Between 1949 and 2001, it produced an estimated 250 million pounds of elemental phosphorus annually. In 1989, as part of what

1120-694: Is impractical and less vibration and rolling resistance. Most of the 13,000 M113s that are still in U.S. Army service have been upgraded to the A3 variant. The current U.S. Army M113 fleet includes a mix of M113A2 and A3 variants and other derivatives equipped with the most recent RISE (reliability improvements for selected equipment) package. The standard RISE package includes an upgraded propulsion system (turbocharged engine and new transmission), greatly improved driver controls (new power brakes and conventional steering controls), external fuel tanks, and 200-amp alternator with four batteries. Additional A3 improvements include

1190-662: Is named after John Bean. In 1928, Bean Spray Pump purchased two companies: the Anderson-Barngrover Co. and Sprague-Sells Co. The Anderson-Barngrover Co. manufactured a sealed can rotary pressure sterilizer and the Sprague-Sells Co. manufactured canning machinery. At this time the company changed its name to Food Machinery Corporation , and began using the initials FMC . In 1948, the company name changed again, to Food Machinery & Chemical Corporation . In 1961, Food Machinery & Chemical Corporation

1260-513: Is prototyping the Eitan (Hebrew for steadfast), an eight-wheeled armored fighting vehicle to replace their M113s. Designed to serve alongside the tracked Namer, the Eitan is planned to be cheaper and lighter, at 35 tons, incorporating an active protection system and a turret. They are expected to begin replacing the M113 starting in 2020. However, due to the slow rate of production of replacement APCs,

1330-634: Is termed the Eastern Michaud Flats Contamination , its 1500-acre plant site was designated by EPA under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) as a Superfund site because of water and land pollution caused by these operations. After working to improve operations and air quality, the company eventually deactivated operations and abandoned the plant and related mine in 2001. Seventeen mines in

1400-683: The 2010 raid on Complexo do Alemão . FMC Corporation Founded in 1883 as the Bean Spray Pump Company in Los Gatos, California , by chemist John Bean. The company's first product was a piston pump . Bean invented the pump to spray insecticide on the many fruit orchards in the area. A Bean sprayer was on display at the Forbes Mill museum in Los Gatos until its closure in 2014. Bean Avenue in downtown Los Gatos

1470-633: The Armored Multi-Purpose Vehicle (AMPV) program to search for a replacement. In 2014, the U.S. Army selected BAE Systems ' proposal of a turretless variant of the Bradley Fighting Vehicle to replace over 2,800 M113s in service. Thousands of M113s continue to see combat service in the Israel Defense Forces , although by 2014 the IDF was seeking to gradually replace many of its 6,000 M113s with

1540-749: The Brazilian EE-9 Cascavel , under license. Bean also manufactured firefighting equipment in the 1960s through the 1980s under the FMC and the Bean names. In 1967, FMC acquired Link-Belt. In 1972, personnel were transferred from ordnance to designing and building recreational vehicles (motorcoaches). The oil crisis and high prices led production to end after five years. FMC also produced fire truck fire pumps and pumper bodies. It had an original equipment manufacturer (OEM) arrangement with Ladder Towers Inc. (LTI) to market aerial ladders. In

1610-558: The Namers , and with the Eitan AFV in 2020. The M113 was developed by FMC Corporation , which had produced the earlier M59 and M75 armored personnel carriers. The M113 bears a very strong resemblance to both of these earlier vehicles. The M75 was too heavy and expensive to be useful, as its weight precluded amphibious use and transport by air. The lightened M59 addressed both of these problems, but ended up with too little armor, and

1680-773: The U.S. invasion of Cambodia on 1 May 1970 and later Laos ( Operation Lam Son 719 ) in 1971; all of which used the M113 as the primary workhorse for moving the ground armies. While operating with cavalry and armor units, the M113s often worked in conjunction with U.S. M48 Patton and M551 Sheridan tanks. During the Vietnam War, U.S. Army gun trucks , along with V-100 armored cars, conducted convoy escorts for military traffic. The USAF used M113 and M113A1 ACAV vehicles in USAF security police squadrons, which provided air base ground defense support in Vietnam. Also, M113s were supplied to

1750-706: The "APC disaster". The vulnerability of the M113 armored personnel carrier to IEDs and RPGs led the IDF to later begin to develop the Namer APC. M113s were used again in the 2006 Lebanon War and Operation Cast Lead . In 2014, during the first wave of the IDF's ground incursion into Gaza in Operation Protective Edge , a Hamas RPG-29 destroyed a fully loaded M113 in Gaza during the Battle of Shuja'iyya , killing all seven Golani Brigade soldiers inside

1820-428: The "Zelda" and "Zelda 2", which are fitted with ERA -suites. The Australian Army refers to its M113A1s as "buckets", "bush taxis" and modified M113A1s fitted with 76 mm turrets as "beasts". The German Army has various nicknames, depending on location and branch of service, including "elephant shoe", "Tank Wedge" and "bathtub". In Spain's Army it is known as "TOA", the acronym of Transporte Oruga Acorazado, which

1890-543: The APCs. On 11 June 1962, the two mechanized units were fielded for the first time. During the Battle of Ap Bac in January 1963, at least fourteen of the exposed .50 caliber gunners aboard the M113s were killed in action, necessitating modifications to improve crew survivability. Makeshift shields formed from metal salvaged from the hulls of sunken ships were soon fitted to the carriers, affording better protection. However, it

1960-854: The ARVN. One notable ARVN unit equipped with the M113 APC, the 3d Armored Cavalry Squadron , earned the Presidential Unit Citation . Additional M113s were supplied to the Cambodian Khmer National Armed Forces , equipped with a turret for the machine gun and a M40 recoilless rifle mounted on the roof. The Army of the Republic of Vietnam also used M113 armored personnel carriers. In 1975, 1381 ARVN M113s were destroyed and captured. Losses in other years are unknown. The Australian Army also used

2030-800: The FMC Corporation merged with the Link-Belt Company. The company produced FMC Link-Belt branded cranes and excavators. In 1986, the Link-Belt Construction Equipment Company was formed as a joint venture between FMC Corporation and Sumitomo Heavy Industries . Between 1965 and 1985 FMC was the owner of the Gunderson metal works in Springfield, Oregon, during that period it was known as the "Marine and Rail Equipment Division of FMC" (MRED), it

2100-491: The IDF in the 1978 South Lebanon conflict . In the 1982 Lebanon War , they saw heavy action. PLO ambushes with RPGs caused extensive casualties because of the tendency of the M113's aluminum armor to catch on fire after being hit by anti-tank weapons. Israeli infantrymen being ferried by M113s learned to quickly dismount and fight on foot when engaged. By the time of the Siege of Beirut , M113s were only used to carry supplies to

2170-733: The IDF is expected to be dependent on the M113 well into the 2020s. The IDF has also increased production of Namer APCs to replace the M113. In the United States, M113s have been adopted by numerous law enforcement agencies. An M113 belonging to the Midland County Sheriff's Department was used in the 2008 raid of the Fundamentalist Church of Jesus Christ of Latter Day Saints compound. The Brazilian Marine Corps 's M113s were used in joint operations with Batalhão de Operações Policiais Especiais during

2240-822: The LVHX2 never went into production, the Marine Corps used the prototypes in their continuous research and development program to develop better equipment for amphibious assault operations. FMC later built the M113 Armored Personnel Carrier (APC), the Bradley Fighting Vehicle , and the XR311 at its former facility in Santa Clara, California . It also purchased the rights to manufacture some foreign military hardware, including

2310-530: The M113 in Vietnam. After initial experiences showed that the crew commander was too vulnerable to fire, the Australians tried a number of different gun shields and turrets, eventually standardizing with the Cadillac-Gage T-50 turret fitted with two .30 cal Browning machine guns, or a single .30-single .50 combination. Other turrets were tried as were various gun shields, the main design of which

2380-481: The M113 are capable of mounting anti-landmine applique armor. The M113A3 was upgraded with internal spall liners and additional applique armor which provided 14.5 mm ballistic protection. In comparison, a modern APC such as the Stryker has all-around 7.62 mm armor-piercing protection, plus 14.5 mm protection on the front, sides, and rear, and a protection against antipersonnel mines. Its weight allows

2450-404: The M113 required only two crewmen, a driver and a commander, and carried 11-15 passengers inside the vehicle. Its main armament was a single .50-caliber (12.7 mm) M2 Browning machine gun operated by the commander. On 30 March 1962, the first batch of 32 M113s arrived in Vietnam, and were sent to two Army of the Republic of Vietnam (ARVN) mechanized rifle companies, each equipped with 15 of

2520-473: The M113 series, making them function as assault guns and fire support; while in many cases still having room inside to carry dismounted infantry or cavalry scouts. The M113 is built of 5083 aircraft-quality aluminum alloy . Aluminum alloy is lighter than steel but requires around three times the thickness for an equivalent level of ballistic protection, meaning the armor of the M113 was only designed for 7.62 mm and shell splinter protection. All variants of

2590-459: The M113, maintaining a fleet of 6,000 of the vehicles. On numerous occasions since their introduction in the late 1960s, the IDF's M113s have proven vulnerable to modern anti-tank missiles, IEDs, and RPGs, resulting in the deaths of many Israeli soldiers riding inside the vehicles. The IDF has nonetheless been unable to replace the use of them in combat operations, due to budget constraints in equipping its large mechanized infantry regiments. Israel

2660-502: The M551s they replaced, have also been modified to resemble enemy tanks and APCs, such as the T-80 and BMP-2 . One of the advantages of the M113 being used to simulate the latter is that the infantry squad can now ride inside the simulated BMP instead of in a truck accompanying a tank masquerading as one, as was often the case with the M551s. The M113 has received a variety of nicknames over

2800-523: The U.S. Army developed kits that allowed the M47 Dragon and BGM-71 TOW anti-tank missile systems to be mounted. In the case of the M47, the system mated to the existing machine gun mount, without having to remove the machine gun. This allowed the commander to use both weapons. A large array of turrets and fixed mounts are available to mount high explosive cannon ranging from 20 mm to 105 mm on to

2870-633: The area have been designated as Superfund sites because of selenium poisoning. FMC Corporation operated a plant in Fridley Minnesota several hundred feet east of the Mississippi river from the 1940s until 1969 where it disposed of waste such as solvents, paint sludge, and plating wastes in an on-site dump. In the early 1980s, contamination from the on-site dump contaminated the Mississippi River, and nearby drinking water for

2940-1076: The city of Minneapolis. FMC Corporation operated a pesticide formulation plant from 1951 until 1986 in Yakima, Washington . From 1952 to 1969, FMC disposed of agricultural pesticides in a pit on site. In 1983 the site was listed in the EPA Superfund list, after groundwater and soil was found to be contaminated with pesticides. After an EPA order, FMC was forced to dispose of 850 tons of contaminated soil between 1988 and 1989. In 1990, EPA required FMC to incinerate soils on-site. At its Dublin Road Site, located in north-western New York in Orleans County, FMC Corporation from 1933 to 1968 disposed of coal ash cinders, laboratory wastes consisting of glass bottles and chemical residues, residues from lime sulfur filtration, building debris and residues from pesticide production areas. These materials contained metals in

3010-449: The early 1960s. The ARVNs had modified the M113s to function as " amphibious light tanks " and not as battle taxis as U.S. designers had intended. Instead of an armored personnel carrier, the ARVN used the carried infantry as extra "dismountable soldiers" in "an oversized tank crew". These "ACAV" sets were eventually adapted to U.S. Army M113s with the arrival of the army's conventional forces in 1965. The vehicles continued to operate in

3080-573: The early 1980s the firefighting apparatus division of FMC tried to expand its role in aerial ladders on fire trucks, leveraging the Link-Belt crane division . FMC's expansion into production of aerial ladders failed: the FMC Fire Apparatus division was shut down in 1990. FMC sells chemical products used by beef and poultry processors to reduce pathogens, such as E. coli and salmonella , on uncooked beef and poultry. FMC obtained

3150-622: The form of salts and pesticides/insecticides. In 2009, CBS 60 Minutes ran an exposé on the use by farmers in Kenya of an FMC-produced pesticide, Furadan , as a poison to kill African lions. The piece suggested that Furadan was a serious threat to the future of the lion population in Africa. FMC has commented extensively on this issue through the media and their websites, including furadanfacts.com. They engaged with government officials, non-governmental organizations , and others to try and resolve

3220-814: The front line, always stopping at least 100 meters from enemy lines. M113s were subsequently used by both the IDF and the South Lebanon Army during the South Lebanon conflict . The IDF utilized M113s during the First Intifada and the Second Intifada . In May 2004, two fully laden IDF M113s were destroyed by IEDs in the Gaza Strip , killing 11 soldiers, all those inside the vehicles on both occasions. This became known in Israel as

3290-603: The incorporation of spall liners and provision for mounting external armor. The M113 has also been adopted to replace the aging fleet of visually modified M551s being used to simulate Russian-made combat vehicles at the U.S. Army's National Training Center in Fort Irwin, California as well as the M60A3s formerly at the Combat Maneuver Training Center near Hohenfels, Germany. These M113s, like

3430-500: The most widely used armored vehicle of the U.S. Army in the Vietnam War and was used to break through heavy thickets in the midst of the jungle to attack and overrun enemy positions. It was largely known as an "APC" or an "ACAV" ( armored cavalry assault vehicle) by the allied forces. The M113 was the first aluminum hull combat vehicle to be put into mass production. Much lighter than earlier similar vehicles, its aluminum armor

3500-472: The role of a light tank and reconnaissance vehicle, and not as designed in theater. Still, the M113 could carry 11 infantrymen inside, with two crewmen operating it. The U.S. Army, after berating the South Vietnamese for flouting battle doctrine, came out with their own ACAV version. This more or less standardized ACAV kit included shields and a circular turret for the .50-caliber M2 machine gun in

3570-427: The same level of protection. An improved T113 design, the T113E1, was adopted by the U.S. Army in 1960 as the "M113". A diesel prototype, T113E2, was put into production in 1964 as the "M113A1", and quickly supplanted the gasoline-engined M113. In 1994, FMC transferred the M113's production over to its newly formed defense subsidiary, United Defense . Then in 2005, United Defense was acquired by BAE Systems . The M113

3640-477: The same speed. It had to carry five tons of cargo across water, through the surf, across the beach, and inland. The vehicle also had to be quickly loaded and unloaded under combat conditions. FMC's Ordnance Division in San Jose, California built and tested two prototypes named "LVHX2 Landing Vehicle, Hydrofoil" for the United States Marine Corps . These were the first amphibious landing vehicles to make use of hydrofoils for high speed ship-to-shore operation. Although

3710-423: The seated troops to fire even while under cover. Although neither the XM701 or XM734 were deemed worthwhile to produce, FMC continued development of their version as the XM765 advanced infantry fighting vehicle (AIFV). The AIFV was sold to a number of third party-users in the 1970s, including the Netherlands, the Philippines and Belgium. Modified versions of the Vietnam War ACAV sets were deployed to Iraq to equip

3780-420: The second largest user of the M113 after the United States, with over 6000 of the vehicles in service. In 1967 some Jordanian M113 were captured in the West Bank during the Six-Day War and were integrated into the Israeli Army. In 1970 Israel started to receive M113A1 to replace the antiquated half-tracks. The IDF M113s were armed with M2 HB machine guns, and two MAG 7.62 mm machine guns on either side of

3850-701: The standard M113s still in service. The circular .50 caliber gun shields have been modified, while the rear port and starboard gun stations have been deleted for service in that region. Some of these modified vehicles have been utilized for convoy escort duties. The M113 has relatively light armor, but it can be augmented with add-on steel plates for improved ballistic protection. Reactive armor and slat armor can be added for protection against rocket-propelled grenades . Band tracks made of rubber are in use by Canadian and other forces to enable stealthy operation, less damage to paved roads, higher speed, less maintenance, access to terrain where operation of wheeled vehicles

3920-400: The track commander (TC) position, two M60 machine guns with shields for the left and right rear positions, and "belly armor"—steel armor bolted from the front bottom extending 1/2 to 2/3 of the way towards the bottom rear of the M113. The two rear machine gunners could fire their weapons while standing inside the rectangular open cargo hatch. This transformed the M113 into a fighting vehicle, but

3990-410: The upper crew compartment door. The M113 took part in the Yom Kippur War in October 1973, when the IDF was equipped with 448 M113s that saw action on the Sinai and Golan fronts. They proved inadequate for direct fighting due to their poor armor protection. In the Battle of Buq'atta most of the 7th Recon Company was wiped out while trying to assault Syrian commandos with their M113s. They were used by

4060-414: The use of a relatively small engine to power the vehicle, a Detroit 6V53 V6 two-stroke diesel engine of 318 cubic inches (5,210 cc) with an Allison TX-100-1 three-speed automatic transmission . This allows the vehicle to carry a large payload cross-country and to be transported by fixed- and rotary-wing aircraft. Original production M113s can swim without deploying flotation curtains, using only

4130-402: The vehicle still suffered from its lightly armored configuration, having never been designed for such a role. Canada also adopted the ACAV kits when employing the M113A2 during peacekeeping operations in the Balkans in the 1990s. In order to improve the fighting ability of the mounted troops, a number of experiments were carried out in the 1960s under the MICV-65 project, which aimed to develop

4200-473: The vehicle. As a result, the IDF faced calls from the Israeli public to build more Namer APCs over the next decade and to gradually reduce the number of M113s used in its future combat operations. A group of 30 Israeli reserve soldiers subsequently notified their commanders that they would refuse to enter the Gaza Strip in M113s. M113s were fielded in Palestine and Lebanon during the Israel–Hamas war . On 15 June 2024, eight soldiers were killed, possibly due to

4270-485: The years. The South Vietnamese Army ( ARVN ) called it the "green dragon". United States troops tended to refer to the M113 simply as a "113" (spoken as "one-one-three"), or a "track". The Israel Defense Forces employ the M113 in many different variants, all designed in Israel, and have given each of them official names, from the baseline "Bardelas" ( lit. Cheetah ) to the "Nagmash" (Hebrew acronym equivalent to "APC"), "Nagman", and "Kasman" variants for urban combat up to

4340-490: Was changed to simply FMC . FMC was awarded a contract to design and build amphibious tracked landing vehicles for the United States Department of War in 1941. FMC ranked 64th among United States corporations in the value of World War II military production contracts. In 1961, the United States Navy 's Bureau of Ships issued bids for a high performance amphibious ship-to-shore cargo carrier capable of moving over water at 35 knots (approx. 40 mph) and over ground at

4410-566: Was designed to be thick enough to protect the crew and passengers against small arms fire, but light enough that the vehicle was air transportable and moderately amphibious. In the U.S. Army, the M113 series have long been replaced as front-line combat vehicles by the M2 and M3 Bradleys , but large numbers are still used in support roles such as armored ambulance, mortar carrier, engineer vehicle, and command vehicle. The U.S. Army's heavy brigade combat teams are equipped with approximately 6,000 M113s and 6,724 Bradleys. The M113's versatility spawned

4480-402: Was developed and produced by the FMC Corporation . The M113 was sent to United States Army Europe in 1961 to replace the mechanized infantry's M59 APCs. The M113 was first used in combat in April 1962 after the United States provided the South Vietnamese army (ARVN) with heavy weaponry such as the M113, under the Military Assistance Command, Vietnam (MACV) program. Eventually, the M113 was

4550-409: Was developed to provide a survivable and reliable light tracked vehicle able to be air-lifted and air-dropped by C-130 and C-141 transport planes. The original concept was that the vehicle would be used solely for transportation, bringing the troops forward under armor and then having them dismount for combat, after which the M113 would retreat to the rear. Entering service with the U.S. Army in 1960,

4620-447: Was found that this material could be penetrated by small arms fire, so subsequent shields were constructed from scrapped armored vehicles. The ARVN 80th Ordnance Unit in South Vietnam developed the shield idea further and commenced engineering general issue gun shields for the M113. These shields became the predecessor to the standardized armored cavalry assault vehicle (or ACAV) variant and were issued to all ARVN mechanized units during

4690-438: Was similar to the gun shield used on the U.S. M113 ACAV version. In addition, the Australians operated an M113 variant fitted with a Saladin armored car turret, with a 76 mm gun as a fire support vehicle, or FSV, for infantry fire support. This has now also been removed from service. Subsequent to Vietnam all Australian M113 troop carriers were fitted with the T50 turret. The FSV was eventually phased out and replaced with

4760-438: Was sold in 1985 to The Greenbrier Companies . In the 1980s, 1990s, and 2000s, FMC Corporation began spinning several of its divisions into separate companies, including United Defense and FMC Technologies , and selling its divisions, including its automotive division to Snap-on Equipment, a division of Snap-on , in 1996. Snap-on renamed the division the "John Bean Company". Bolens was sold to Troy-Bilt in 1988. FMC entered

4830-532: Was the first U.S. Army armor unit deployed to Vietnam. It originally consisted of three platoons of M113s and a platoon of 90 mm M56 Scorpion self-propelled anti-tank guns (SPAT). It was the only independent armor company in the history of the U.S. Army. Upon the company's arrival in Vietnam, a fourth line platoon was added; this was equipped with M106 4.2 in. mortar carriers (modified M113s). The mortar platoon often operated with Brigade infantry units to provide indirect fire support. It also deployed at times as

4900-426: Was unreliable as a result of efforts to reduce its cost. The Army was looking for a vehicle that combined the best features of both designs, the "airborne armored multi-purpose vehicle family" (AAM-PVF) of all-purpose, all-terrain armored fighting vehicles. FMC had been working with Kaiser Aluminum and Chemical Co. in the late 1950s to develop suitable aluminum armor. It was known that use of this armor could produce
