73-638: The SAM-R was retired by the U.S. military in the mid-2010s and thus is no longer in service, having been replaced by the M27 IAR . The Squad Advanced Marksman and his weapon, the Squad Advanced Marksman Rifle, was the product of extensive experimentation by the Marine Corps Warfighting Laboratory (MCWL) of the addition of a designated marksman to a Marine squad. The concept of a designated marksman

146-678: A Leupold TS-30A2 Mark 4 MR/T 2.5-8x36mm variable power scope, the same optic fitted on the Mk 12 Special Purpose Rifle . Although certain selected M27s had been employed as marksman rifles since 2016, the M38 version uses an optic with greater magnification. The naming of the M38 followed a similar convention to the M27, being named after the 3rd Battalion, 8th Marines unit that tested the rifle. By April 2018, fielding to all three Marine expeditionary forces had been completed. One M38 marksman version, fitted with

219-528: A brief intensive artillery preparation would be followed by small, autonomous teams of stormtroopers , who would covertly penetrate defensive lines. The Germans used their stormtroopers organized into squads at the lowest levels to provide a cohesive strike force in breaking through Allied lines. The British and Canadian troops on the Western Front started dividing platoons into sections after the Battle of

292-713: A concept to suppress every weapon in an infantry battalion. Exercises showed that having all weapons suppressed improved squad communication and surprise during engagements. Disadvantages included additional heat and weight, increased maintenance, and the greater cost of equipping so many troops with the attachment. In July 2020, the Marine Corps announced it would be ordering suppressors for use by all M27s used by close combat units. The Marines began to roll out suppressors for all M27s in infantry, reconnaissance and special operations units in December 2020. The QDSS, in use since

365-404: A fireteam generally spreads over a distance of 50 metres (160 ft), while in defensive positions the team can cover up to the range of its weapons or the limits of visibility, whichever is less. In open terrain, up to 500 metres (1,600 ft) can be covered by an effective team, although detection range limits effectiveness beyond 100 metres (330 ft) or so without special equipment. A team

438-703: A larger unit. Successful fireteam employment relies on quality small unit training for soldiers, experience of fireteam members operating together, sufficient communications infrastructure, and a quality non-commissioned officer corps to provide tactical leadership for the team. These requirements have led to successful use of the fireteam concept by more professional militaries. It is less useful for armies employing massed infantry formations, or with significant conscription. Conscription makes fireteam development difficult, as team members are more effective as they build experience over time working together and building personal bonds. In combat, while attacking or maneuvering,

511-662: A noncaliber-specific reticle and an illuminated or nonilluminated aim-point and is intended to supplement the attrition and replacement of the older ACOG RCO and SDO sights for weapons including the M27. Fielding of the VCOG SCO began in January 2021. In December 2021, the USMC signaled intention to acquire 19,000 units of the SCO. In January 2017, a USMC unit deployed with KAC NT4 QDSS suppressors mounted to their M27 rifles as part of

584-588: A portion of the M249 light machine guns employed by automatic riflemen within Infantry and Light Armored Reconnaissance Battalions. Approximately 8,000–10,000 M249s will remain in service with the Marine Corps to be used at the discretion of company commanders. In December 2017, the Marine Corps announced that it would equip every member of an infantry squad with the M27, supplanting the M4 carbine which would be retained at

657-548: A position where the enemy embrasure could be attacked with grenades. The Chasseur tactics were proven during the Petain Offensive of 1917. Survivors of these French Chasseur units taught these tactics to American infantry, who used them with effectiveness at St. Mihiel and the Argonne. It was typical of a fireteam in this era to consist of four infantrymen: two assaulters with carbines, one grenadier, and one sapper. In

730-530: A pre-solicitation notice for the M27. "The new pre-solicitation notice of 50,184 [M27s]", said Woodburn, "is [meant] to up the production capacity that H&K must be able to meet as the sole-source provider [of the M27], should the Marines decide to order more in the future." At SHOT Show 2018, the Marine Corps announced that the deal with H&K to produce 11,000 M27s for the Marine Corps had been finalized and that

803-482: A recruit or replacement. The new soldier learns from the experienced soldier how to properly perform the everyday tasks and responsibilities of his assignment. In the old colonial forces (like the French Foreign Legion ) it was a means of imposing order. The pair were responsible for each other – if one member broke the rules or deserted, the other would be punished for not preventing it. According to

876-644: A role where it replaced the Squad Advanced Marksman Rifle . Additionally, the free-floating barrel offers improved accuracy at approximately 2  MOA compared with 4.5 MOA for M16A4 rifles. The M27 is based on the H&;K HK416 . It features a gas-operated short-stroke piston action with a rotating bolt and a free-floating barrel. The handguard has four MIL-STD-1913 Picatinny rails for use with accessories and optics. Alternate calibers other than 5.56 mm are being considered for

949-684: A scope and QDSS suppressor, is to be fielded per infantry squad to engage targets out to 600 meters. Full operational capability is planned for September 2018. [REDACTED]  This article incorporates public domain material from websites or documents of the United States Marine Corps . Fireteam#Marine Corps A fireteam or fire team is a small modern military subordinated element of infantry designed to optimize " NCO initiative", " combined arms ", " bounding overwatch " and " fire and movement " tactical doctrine in combat. Depending on mission requirements,

1022-427: A scout (marksman/grenadier) armed with an M1903 Springfield with a rifle grenade discharger, and a team leader armed with an M1 carbine or M1 Thompson submachine gun. Their later misuse as conventional infantry negated their special training and fighting skill and their use as "fire brigades" against larger enemy forces negated their advantages in aggressiveness and firepower. Meanwhile, the communist Chinese established

1095-472: A separate unit in its own right, although fireteams or fireteam-sized units are often used for reconnaissance tasks, special operations, and urban patrols (usually being to referred to as a "brick" in the latter scenario). The U.S. Army particularly emphasizes the fireteam concept. Per U.S. Army doctrine a typical fire team consists of four soldiers. In a stryker brigade combat team's (SBCT) infantry rifle companies, one man in each rifle squad fireteam

1168-820: A typical "standard" fireteam consists of four or fewer members: an automatic rifleman , a grenadier , a rifleman , and a designated fireteam leader. The role of each fireteam leader is to ensure that the fireteam operates as a cohesive unit. Two or three fireteams are organized into a section or squad in co-ordinated operations, which is led by a squad leader . Historically, militaries with strong reliance and emphasis on decentralized NCO -corp institutions and effective "bottom-up" fireteam organization command structures have had significantly better combat performance from their infantry units in comparison to militaries limited to officer -reliant operations, traditionally larger units lacking NCO-leadership and "top-down" centralized-command structures. Fireteam organization addresses

1241-514: Is an HK416 variant with accessories required by the Marine Corps. It is issued with the Blue Force Gear Vickers Combat Applications sling and rail sling mounts, AIM Manta Rail Covers, Harris bipod, KAC backup iron sights, a foregrip, and bayonet lug . The M27 initially had a grip pod, which is a foregrip with bipod legs inside, but it was replaced by a separate foregrip and bipod. The standard optic

1314-531: Is effective so long as its primary weapon remains operational. In the Canadian Army , "fireteam" refers to two soldiers paired for fire and movement. Two fireteams form an "assault group", which is analogous to most other militaries' understanding of a fireteam; two assault groups and a vehicle group of one driver and one gunner form a section of ten soldiers. People's Liberation Army forces traditionally used three-man "cells" (equivalent to fireteams) as

1387-428: Is either the squad anti-armour specialist (RMAT) armed with an FGM-148 Javelin , or the squad designated marksman (DM) who carries an M4 carbine and M14 rifle . In both cases, these two positions replace the basic rifleman of the standard rifle squad. The United States Marine Corps doctrine dictates that any active fireteam will include at least one 2-man gunnery-team and summarizes its fireteam organization with

1460-525: Is less susceptible to malfunctions compared to previous internal piston M4- and M16-style weapons. IAR gunners consider the rifle-grade accuracy to be a significant improvement over the SAW, despite the loss of sustained firing. Due to budget limitations, the Marine Corps is looking at ways to implement the IAR as a multipurpose weapon. Suggestions included use as an automatic rifle and as a designated marksman rifle ,

1533-723: Is more controllable on fully automatic than the M249. Concern of volume of fire loss was made up through training courses developed in December 2010. With the M249 SAW , the idea of suppression was volume of fire and the sound of the machine gun. With the M27 IAR, the idea of suppression shifts to engaging with precision fire, as it has rifle accuracy at long range and fully automatic fire at short range. Shooters transitioned from long-range precision fire at 700 meters to short-to-medium-range suppressive fire at 200 meters (660 ft), both while in

The later SAM-R was roughly a modified M16A4 pattern rifle: M27 IAR The M27 Infantry Automatic Rifle ( IAR ) is a 5.56mm , select-fire assault rifle , based on the HK416 by Heckler & Koch . It is used by the United States Marine Corps (USMC) and is intended to be issued to all infantry riflemen as well as automatic riflemen . The USMC initially planned to purchase 6,500 M27s to replace

1679-568: Is still in use. Fireteams have their origins in the early 20th century. From the Napoleonic Wars until World War I , military tactics involved central control of large numbers of soldiers in mass formation where small units were given little initiative. Groups of four soldiers were mainly employed for guard duty, or as bodyguards for VIPs. In the Roman Army they were referred to as quaternio (Greek τετράδιον). Skirmishers in

1752-558: Is the Trijicon Advanced Combat Optical Gunsight (ACOG) Squad Day Optic (SDO), officially designated the Sight Unit, SU-258/PVQ [TA11SDO]. It is a 3.5×35 machine gun optic that has a Ruggedized Miniature Reflex (RMR [RM05 RMR]) sight screwed on top for close-quarters engagements under 100 meters. Created for the SAW, the day optic offers slightly less magnification but longer eye relief than

1825-410: Is the reconnaissance and maneuver unit. The teams employ bounding overwatch , with one element covering as the other moves. The team leaders have handheld radios so the elements can stay in contact with each other, as well as with the section leader's backpack radio set. The most common symbol of the modern French junior NCO ( chef d'équipe ) has been a radio hanging around their neck. Infantry units of

1898-519: The British Army , Royal Marines and RAF Regiment introduced the fireteam concept following the adoption of the SA80 rifle and light support weapon. An infantry section of eight men contains two fireteams, Charlie and Delta, each comprising an NCO (corporal or lance corporal ) and three privates. The fireteam is generally used as a subdivision of the section for fire and maneuver rather than as

1971-630: The Knight's Armament Company Free-Floating Rail Adapter System) and an M16A1 trigger assembly (semi and full-auto functioning). A number of day optics were used initially, which included Hensoldt Blitz, Leupold CQ/T, ACOG , Leupold TS-30A1 and ultimately the Leupold TS-30A2. The test night optic was the AN/PVS-17B, apparently now being fielded with USMC combat units though the AN/PVS-22

In December 2009, the H&;K weapon won the competition and entered into a five-month period of final testing. In the summer of 2010, it was formally designated as the M27 Infantry Automatic Rifle. After

There was some talk of adopting a weapon such along the same lines as the Mk 11 Mod 0 , but instead that transferred over to a possible replacement for USMC personnel now using the Designated Marksman Rifle (DMR), a variant of the M14 . The SAM-Rs were assembled by the Precision Weapons Section of

2336-617: The National Revolutionary Army in action against the Imperial Japanese Army , brought these ideas back to the US when the country entered World War II . Under his command, the 2nd Marine Raider battalion were issued with the semi-automatic M1 Garand rifle and were organized in the standard 4-man fireteam (although it was called firegroup) concept, 3 firegroups to a squad with a squad leader. A firegroup

2409-560: The Thompson submachine gun and Winchester Model 1912 shotgun was popular with the Marines as a point-defense weapon for countering ambush by Nicaraguan guerrillas within the thick vegetation that could provide cover for a quick overrun of a patrol. A team of four men armed with these weapons had proven more effective in terms of firepower and maneuverability than the standard nine-man rifle squad.

The Infantry Automatic Rifle program began on 14 July 2005, when the Marine Corps sent Requests For Information to arms manufacturers. Characteristics desired in the weapon included portability and maneuverability; similarity in appearance to other rifles in the squad, reducing

As of December 2020, it has already obtained 13,700 units. The M38 Squad Designated Marksman rifle (M38 SDMR) is essentially the same as the M27 IAR and retains its selective fire capabilities. The only difference is that it is fitted with

2628-562: The ACOG Rifle Combat Optic (RCO) on M16s and M4s. The longer relief helps reduce injury risk from recoil . In February 2020, it was announced that Trijicon would deliver approximately 19,000 units of its newer 1-8x28 Variable Combat Optical Gunsight (VCOG) between 2021 and 2023 under the SU-281/PVQ [VCOG 1x8-28] Squad Common Optic (SCO) designation. The SU-281/PVQ is a variable-power magnified day optic that comprises

2701-547: The B team provided suppressive fire. Suppressive fire from the BAR would be supplemented by fire from the rifles of his team as he reloaded, and could be further supplemented by platoon medium machine guns. The US Army Rangers and Special Service Force adopted an early fireteam concept when on campaign in Italy and France. Each squad sub-unit of four or five men was heavily armed, composed of a two-man BAR automatic rifleman and assistant,

2774-572: The M249 SAW within the infantry and those who advocate that a lighter, more maneuverable, and accurate weapon is sufficient to support offensive operations at the squad level. With the M249 SAW, the doctrine of fire suppression is the sound of continuous fire with rounds landing close to the enemy. While the M249's volume of fire may be greater, it is less accurate. Experienced troops who have dealt with incoming fire are less likely to take cover from incoming rounds if they are not close enough. With an IAR,

2847-628: The M249. In early 2017, Commandant of the Marine Corps General Robert Neller said he wanted to equip every " 0311 " rifleman with an M27 IAR. Because of that, the Marine Corps issued a request in early 2017 for 11,000 M27 IARs from H&K. According to Chris Woodburn, deputy of the Maneuver Branch, Fires and Maneuver Integration at Marine Corps Combat Development Command , "The new order will replace all M4s in every infantry squad with an M27, except for

2920-616: The M27 IAR would be adopted as the standard issue service rifle of the Marine Corps infantry, largely replacing the M4, which would be retained at platoon and company leadership levels. In 2019, it was reported that the last of the M27s would arrive at the Marine Corps inventory and are expected to be in the hands of each infantryman from platoon commander and below by mid-2021. Ultimately, the Marines bought just over 14,000 M27s, Manny Pacheco, spokesman for Marine Corps Systems Command, told Marine Corps Times . While Marine Corps Systems Command

2993-424: The M27. The M27 usually draws ammunition from a standard 30-round STANAG magazine. The improved STANAG magazine with the tan-colored anti-tilt follower is favored over the previous version with the green follower because it can be inserted more easily, and the anti-tilt follower can handle high rates of fully automatic fire with less chance of malfunction. There have been issues with some STANAG magazines sticking in

3066-708: The Napoleonic War would often work in teams of two, ranging ahead of the main group and providing covering fire for each other. During World War I, trench warfare resulted in a stalemate on the Western Front . In order to combat this stalemate, the Germans developed a doctrinal innovation known as infiltration tactics (based on the Russian tactics used in the Brusilov Offensive ), in which

3139-438: The PMAG. Because the M27 cannot be fed from the widely-used M2 PMAG magazines that M4s or M16 rifles in the squad could take, the Marines banned the polymer PMAG for issue to prevent interchangeability issues. In response, Magpul began the process of arranging verification and official testing for their improved PMAG 30 GEN M3 magazine, which is compatible with both the M27 and M16-series rifles. After Marine Corps testing of

After a lengthy period of debate over the role of accuracy vs. suppressive fire in the Marines, they adopted a new doctrine and weapon in the more accurate M27 Infantry Automatic Rifle for their service rifle in September 2018 and it will replace most of the M4 Carbine for

3285-573: The Somme in 1916. (This idea was later further developed in World War II ). French Chasseur units in WWI were organized into fireteams, equipped with a light machine gun (Chauchat) team and grenades, to destroy German fire positions by fire (not assault) at up to 200 meters using rifle grenades. The light machine gun team would put suppressive fire on the enemy position, while the grenadier team moved to

3358-572: The Special Air Service. It consists of two soldiers with one soldier acting as senior of the two fighters (decided amongst the two or by their superior). A fireteam in turn consists of at least two fire and maneuver teams, and a squad of two or more fireteams. It may be known in the United States as a fire and maneuver team . This concept has not been widely utilized. The United States and most Commonwealth armies mainly rely on

3431-710: The Weapons Training Battalion at Marine Corps Base Quantico . For the War on Terrorism , the approximately 100 assembled SAM-Rs were sent to the 22nd , 24th , and 26th Marine Expeditionary Units (MEU) of II Marine Expeditionary Force (MEF), which is located at Camp Lejeune, North Carolina. Squad Advanced Marksmen of I MEF , which is based at Camp Pendleton, California, made do with M16A4s with KAC M5 RAS forearms and TA31F ACOGs . Some SAM-Rs are nicknamed "West Coast SAM-Rs", though they are simply M16A4s with optics and bipods and not an 'accurized' rifle like

3504-495: The attack: three men would form one fireteam, and three fireteams one squad. A Chinese platoon, consisting of 50 men, would form three ranks of such fireteams, which would be employed to attack "one point" from "two sides." Each cell carries at least one automatic weapon (In the Korean War, it was submachine guns or light machine guns . In the early to mid-cold war, it was assault rifles or squad automatic weapons ), while

3577-568: The concept of fire teams forming a squad. Such a team is known as a Lahingpaar or battle pair. Until 2015 in the Finnish Defence Forces , three taistelupari (combat pairs) formed a squad along with a squad leader. A three-man fireteam is now the smallest standard unit in Finnish infantry doctrine. The French Army has the concept of a binôme ('pair'). In the regular forces it is the pairing of an experienced soldier with

3650-634: The conclusion of the Limited User Evaluation (LUE) and ordered the replacement of the M249 LMG by the M27. Fielding of the approximately 6,500 M27 units was completed by 2013, at a cost of $ 13 million. Each M27 gunner was to be equipped with around 22 30-round magazines of the type currently in use with the M16 and M4 carbine , approximating the combat load of an M249 SAW gunner. The M27 gunner would not be expected to carry all 22 magazines. The individual combat load would be determined at

3723-551: The doctrine is that lower volume of fire is needed with better accuracy. Fewer rounds need to be used, and automatic riflemen can remain in combat longer and in more situations. The IAR was initially fielded in December 2010. 1st Battalion, 3rd Marines were deployed to Afghanistan in April 2011 with 84 IARs. Former SAW gunners initially did not like the M27 but appreciated it as time went on. It weighed 9 lb (4 kg) loaded, compared to 22 lb (10 kg) for an M249, which

The rifles are distributed one per squad. The original test weapon was a modified M16A2 rifle with a free-floated 1:7 stainless steel match grade heavy barrel, a "Mil-Std-1913 modular rail system" (this most likely implies the use of

3869-604: The inter-war years, United States Marine Corps Captain Evans F. Carlson and Merritt A. Edson are believed to have developed the fireteam concept during the United States occupation of Nicaragua (1912–1933). At that time the US Marine squad consisted of a Corporal and seven Marines all armed with a bolt-action M1903 Springfield rifle and an automatic rifleman armed with a Browning Automatic Rifle . The introduction of

3942-431: The likelihood that the gunner will receive special attention from the enemy; facilitation of the gunner's participation in counterinsurgency operations ; and capability of maintaining a high volume of fire. An initial requirement for a magazine with a minimum capacity of 100 rounds was dropped in favor of the 30-round STANAG magazine because, at the start of testing, available 100-round magazines were unreliable. Caliber

4015-401: The magwell, especially when painted or damaged. While a rifleman normally carries seven 30-round magazines, an IAR gunner has to carry up to 16 and may carry as many as 21 due to the requirements of the role and fully automatic rate of fire. The magazine well has a flared opening that aids in magazine insertion. A PMAG 30 GEN M2 magazine cannot be inserted because of the frontal plastic bevel on

Seabee units may be attached to Marine Corps units. Many other armed forces see

4161-434: The most basic organization upon which modern infantry units are built in the British Army , Royal Air Force Regiment , Royal Marines , United States Army , United States Marine Corps , United States Air Force Security Forces , Canadian Forces , and Australian Army . The concept of the fireteam is based on the need for tactical flexibility in infantry operations. A fireteam is capable of autonomous operations as part of

4234-695: The platoon leadership positions and above. In 1999, a Universal Need Statement was issued for an IAR. Around 2000, the 1st Marine Division’s 2nd Battalion, 7th Marines Regiment conducted initial, limited IAR trials which confirmed the desirability of a light automatic rifle. The key difference between a lighter infantry rifle and a more heavily built automatic rifle is the ability of the latter to maintain sustained continuous fire without stoppages, overheating, or loss of accuracy. Experiences in Iraq and Afghanistan resulted in formal requests for recommendations. The Universal Need Statement spent six years going through

4307-483: The prone position. Some gunners in combat have been used as designated marksmen . An M27 gunner with one aimed shot has the effect of three or four automatic shots from the SAW and still has the option of a heavier volume with an accurate grouping . Marines issued with the M27 enjoy its similarities to other M4-style weapons in service. Its gas-operated short-stroke piston action runs cooler and more cleanly, requires less maintenance, has less internal parts wear, and

An example of a People's Volunteer Army fireteam in the late Korean War, The French section ( groupe de combat – "combat group") is divided into two teams. The "fire team" ( équipe de feu ) is based around the section-level automatic rifle or light machine gun. The "shock team" ( équipe de choc ), made up of riflemen armed with rifle grenades or disposable rocket launchers,

4526-467: The same rate of fire. In a firefight, squad members carrying extra magazines for the M27 might not always be in a position to supply them to the gunner. Further, the SAW was already a battle-proven weapon. He regarded it as significant that the Army had chosen not to pursue the IAR concept. The notion that the M27 represents a reduction in suppressive fire has spawned considerable debate between proponents of

4599-479: The smallest military formation and such organization was widely employed throughout the Second Sino-Japanese War , Chinese Civil War , Korean War , Sino-Indian War , Vietnam War as well as Sino-Vietnamese War . It is unofficially named the "three-three organization". （ Chinese : 三三制 ） In Chinese sources, this tactic is referred to as "three-three fireteams", after the composition of

4672-438: The squad as the smallest military unit; some countries' armies have a pair consisting of two soldiers as the smallest military unit. In others a fireteam is composed of two pairs of soldiers (fire and maneuver team) forming a fireteam. Vietnamese communist forces, who received extensive advisory support from Chinese communists, also adopted a fireteam concept similar to that of Chinese, known as " tam tam chế ", and such organization

4745-425: The squad leader and two scouts, the support B "Baker" team of the BAR gunner, assistant gunner, and ammunition bearer, and C "Charlie" team of the assistant squad leader, also serving as the anti-tank grenadier, and five riflemen, one of whom served as the alternate anti-tank grenadier). In an assault the A team would provide overwatch and security or assist the C team in the assault, as the squad leader directed, while

The timeline for funding was planned for fiscal years 2019 and 2020, with the Corps acquiring some of the rifles in fiscal year 2018. As of August 2017, officials stated that "riflemen are the top priority", but that the M27 "will be in the hands of combat engineers and light armored reconnaissance battalion scouts next." The Corps later issued

A battle pair is the smallest unit above the individual soldier, in the modern era chiefly employed by Baltic militaries and special forces like

4964-400: The unit level and was expected to vary by unit, based on results of evaluations. Though program officials were aware that switching from the belt-fed M249 would result in a loss of suppressive fire capability, Charles Clark III, of the Marine Corps' Combat Development and Integration Office, cited the substantially increased accuracy of the M27 as a significant factor in the decision to replace
