With more than 80,000 units produced worldwide, the M113 was the most prolific tracked vehicule produced snce WWII, only surpassed by the more recent M2 Bradley.  The wartime Universal "Bren" Carrier was even more prolific with 113,000 being assembled but it never had the M113 versatility and general performances.


The success of the M113 layed in lessons learned from previous APCs :


The M39 used the hull of the M18 Hellcat tank destroyer with the turret replaced by a open-topped superstructure with a .50cal machine gun ring mount at the front. The M39 served as a personnel and cargo carrier or artillery towing vehicle





It had 51,000 lb of combat weight, Carrying 24 fully equipped infantrymen at a combat weight of 51,000 lb, it was aremed with a bow M1919H4 .30cal LMG and a rear .50cal M1920 HMG.



Armed with a ring-mounted .50cal M2HB (1800 rounds), its rear bay held 10 fully-equipped soldiers, along with a M20 Bazooka and 10 spare rockets, as well as large provisions for the soldier's M1 Garand/M2 carbine.  Rapidly transfered to training units.

From mid-1953, a few served in Korea showing their being too heavy to be amphibious or air transportable, tall and costly, albeit more reliable than the M59 that replaced it.

600 M75s went to Belgium, only non-US user, where they served till the 1980s, with 77 listed remaining ty 1990.



FMC, a sub-contractor for 700 of the 1730 Intl Harvester's M75, developped their own design in 1953.  Lighter, air transportable, amphibious and cheaper, it had a weaker armor than the M75 it replaced and had unreliable engines.  Armed with a ring-mounted .50cal M2HB (2200 rounds) it carried 10 fully equipped soldiers.  Widely used in Vietnam but soon eclipsed by the M113.  Contrary to the M75, the M59 saw a few exports :

– Brazil 500 – Greece 200
– Ethiopia 150 – Turkey 1550

The next FMC design thus adressed these issues, and 3 prototypes were made in 1959 : two T113 (one being better armoured than the other) and the aluminium & steel T117. In 1960, the better armoured T113 was chosen for mass-production and pressed into service in 1961 as the M113.

The then new M113 was battle tested in Vietnam (1962) and widely used from 1964 to 1973, including the ACAV variant. The 1964 diesel powered M113A1 supplanted the 1960 gasoline version; the 1979 upgraded M113A2 improved mobility and protection and the 1987 M113A3 further improved its general survivability.


As an Armoured Personal Carrier (APC), the M113 is lightly armed : a ring mounted .50 cal M2HB on the centerline.  However light, the gun is capable to deal with infantry, buildings, low-flying aicrafts and helicopters, as well as lightly protected vehicles in general.  But there has been variants with heavier armament.  To only mention a few :

  50 cal Maxon quad an Turkis adaptation carried out in the 1970s
  57 cal ZPU-4 quad an Lebanese mod using the Soviet 14.5mm AA quad gun
  20 mm autocannon Rheinmetall MK2020   or Oerlikon Kan 48/73
  20 mm gatling gun M163 SPAAG with a M61 Vulcan gun
  23 mm ZSU-2 twin an Lebanese mod using the Soviet 23mm AA twin gun
  25 mm autocannon Oerlikon-Contraves in an Italian Oto Melara turret
  25 mm autocannon KBA-B02 turret or Elbit remote ctrld gun/Scorpion turret
  37 mm gatling gun T249 SPAAG with a T250 Vigilante gun
  40 mm AGL automatic grenade launcher instead of the .50 HMG
  76 mm tank gun short barrel in an Alvis Saladin turret
105 mm howitzer variant exclusive to the (West) German Army

With its low maintenance costs due to standardization, the M113 soon became a “jack-off-all-trades” and the basis of multiple variants carrying very different weapons, among them surface-to-air missiles and surface-to-surface missiles to mention the most radical variations.

Production & Main Variants

1961 - M113
Similar in apperance to the following versions, the 1961 base M113 version was propelled by a 209 hp V8 gasoline engine. Designed to swim without flotation screens, only deploying their front trim vane and using tracks for propulsion and direction change, it was tested in Viet-Nâm and reports helped to create the modified M113A1.

1963 - M113 ACAV

Developed during the Viet-Nâm war in response to casualties observed with the exposed gunner/commander and other observed losses the ACAV (Armored Cavalry Assault Vehicle) received a set of armour shield protection surrounding the gunner.

1964 - M113A1
A more powerful while much sober 6V-53 Detroit Diesel engine gave it a much extended range and reduced fire hazard.  “A1” was used on all diesel equipped variants.

1979 - M113A2
The A2 encompassed a whole range of modifications, including better engine cooling, higher strength torsion bars for a higher ground clearance, fitted in addition with shock absorbers for smoothier rides. For extended range, armored fuel tanks were fitted externally on both sides of the rear ramp. This also help to free 16 cubic feet of internal space. The M113A2 overall weight rose to 25,880 lbs which altered its amphibious characteristics without suppressing it. A 2×2 Smoke grenade launcher was added for self-concealment. Many earlier vehicles were upgraded to this standard.

1987 - M113A3
Although showing its age by the end of the 1980s, the M113 was still irreplaceable.  A program was launched to extend its service life for another 20 years. A steering yoke replaced the old of laterals and a more powerful 6V-53T Detroit Diesel replaced the older powerplant which helped reclaimed the performances losses after the introduction of the heavier A2.  Extra external fuel tanks were added whereas internal spall liners were fitted for better crew and infantry protection. The A3 also became an upgrade for older vehicles therefore production figures are ellusive. This was the last upgrade of the M113, still in service with some units of the US Army and Marines. Large parts of the stocks were also sold abroad with the end of the cold war, scrapped, or sunk as artificial reefs. Many M113 replaced the ageing M551 visually modified (vismod) simulating Russian-made T-80 or BMPs at the U.S. Army’s National Training Center in Fort Irwin, California. These have in addition the advantage of still allowing an infantry squad to be carried in the simulated BMP-2 contrary to the M551s.

Since the Vietnam War, ACAV kits has been used in many occasions, the latest of which was Iraq for standard M113s in service by the time of Operation Desert Shield (1991). The caliber .50 gun shields were modified and the rear port and starboard gun stations deleted. Most served for convoy escort duties and urban combat.  Early on, the relatively weak armour was augmented by add-on steel plates (IDF started this out).  Reactive armor and slat armor were also added for effective protection against RPGs, especially useful in the 2003-2013 war in Iraq and Afghanistan.  Windowed gunshields were also developed by a local armorer in Iraq which recalls the M1A2 Abrams’s TUSK set.  Discreet rubber band tracks are used by Canada and others for stealth night operations but also to decrease road damage, while allowing for higher speed, better grip and mobility, and easier maintenance by much reducing the level of vibrations.

1994 - M113A4 or MTVL
Also called the M113A3+ and Mobile Tactical Light Vehicle (MTVL) this post-cold-war project was an attempt to modernize the APC basic design in several directions. It saw a chassis lengthened 34 inches with an additional road wheel and built by private venture as a “production-tooled demonstrator” by the United Defense group.  The US Army wasnt interested but it was copied by Pakistan, Turkey, Egypt as it just needed minor retooling of their local M113 manufacturing plants. Canada and Australia, also used stretched-out M113 versions.  In total Canada ordered 183 vehicles to be converted to this new standard. These vehicles are also equipped with the compact Cadillac-Gage one-man power assisted 12.7 mm (.50 cal) turret.

Other modifications includes increased power and improved suspensions, not much increased ground pressure despite a 4 tons more in weight gain. Optional bolt-on steel armour could be added. The revied armament comprised two C6 7.62 mm light machine-gun (LMG) and two banks of four electrically fired 76 mm multi-purpose grenade launchers (smoke, white phosphorus, frag rounds). Another variant uses the Protected Weapon System [PWS] instead of the turret, a remotely controlled weapon station with a 7.62 mm C6 LMG.  In addition a digital night observation sight is given to the driver and a light intensification sight for the commander.  The “M113A4” (standard chassis) is also produced by FNSS of Turkey in 11 versions, all modernized.  In another register, the M113 is also used by NASA (for emergency evacuation of astronauts during a launch pad emergency), and some police SWAT units.

American M113 variants

As stated above, the M113 showed great capability for transformation.  More than a hundred variants and sub-variants are known internationally, and there will be all covered here. Some only concerned a few vehicles while others contributed to produce an all-new mass-produced specialized vehicle all by itself. Some of these at least in the USA, like often with specialized vehicle, are still in service today whereas the APC variant is no more.

M58 Wolf
A specialized vehicle equipped for laying a smoke screen, with internal tanks and a generator. Much of the cargo area is occupied by this system.

M48 Chapparral (SPAAML)
Anti-aircraft (missile) variant with the rear section entirely modified to carry a launcher for four MIM-72A/M48 Chaparral missiles and reloads inside.

M106 Mortar Carrier
The standard mortar-carrier version. The M30 mortar is mounted on a turntable in the rear cargo bay, open by a three-part circular hatch. The mortar also had the capability to be loaded off and fired dismounted. The US Army uses now the upgraded M1064A3 with M121 120 mm mortar. The M106 led to a sub-variant, the M125, similar but armed with a lighter M29 81 mm mortar carrying more ammo.  The XM106 Self-propelled Mortar was originally known as the T257E1 before standardization. The M106A1 had the diesel engine, while the M106A2 was to the A2 standard.

M132 Flamethrower
The flamethrower variant, with a turret carrying an M10-8 flamethrower and a coaxial M73 machine gun, with fuel and pressure tanks in the rear of hull. They have been partly upgraded to the A1 standard (M132A1). They served in Vietnam.

M150 TOW Tank Hunter
Tank hunter (ATGM) variant equipped with a single TOW missile launcher installed right before the rear crew hatch, with a set of missiles in reserve inside. Secondary armament is still the cal.50 at the usual position. Also used by several countries or developed as a kit. A sub-variant was later developed with two TOW missiles.

SPAAG version (Self propelled Anti-Aircraft, Gun), armed with a 20 mm M61 Vulcan autocannon in turret installed on a M168 mount, on a M741 carrier. This Vulcan Air Defense System (VADS) had rapid fire capabilities, and is very accurate up to a 2 miles range (3210 m).  Like all SPAAGs it could also be used against land targets with deadly efficiency.

M548 Cargo
The unarmored cargo carrier equipped with a modified heavy duty rear cargo bed.

M577 Command
Command & control vehicle, with a completely modified after section, housing new surveillance equipments, operators, a map table, additional long-range radios and a generator.

M579 Fitter CEV
A Combat Engineering version, with a fitter and repair equipments, like a crane. Although never accepted in US Army service, it was largely exported.

M806 ARV
Repair and recovery vehicle equipped with an internal winch, two earth anchors mounted on the rear hull.

M113 MBT (Vismod)
This Vismod (“Visual Modification”) version is disguised as a Bradley IFV, equipped with a fake turret with false ERA blocks, MILES gear, MGSS/TWGSS system, which is used for training. Also called M113 OSV (OPFOR Surrogate Vehicle or “OSV”) in force-on-force training.

Australia (around 700 in service now)

The Australian Forces were among the first users of the M113A1, rapidly bringing them into action in Vietnam in the early 1970s. Modernization and improvement packages were quickly applied to the serie, like the addition of a AN/VIC-1 com set, large dust filters, removal of crew compartment heaters, 600 kgs of belly armour added for mine protection, and heavy steel tracks. Also, most turned out as heavily armed APCs, with the addition of the Cadillac-Gage T-50 turret (cal.50 +cal.30 or twin .30), or heavier turrets in the case of the following variants:

M113A1 FSV
Fire Support Vehicle. This variant was a practical IFV. These were vehicles modified to receive the Alvis Saladin turret, armed with a short barrel 76 mm. it was used in the early 1970s by the Royal Australian Armoured Corps which named it the “Beast”.

M113A1 LRV
Light Reconnaisse Vehicle equipped with the V150 Cadillac-Gage T-50 turret with the cal.50/cal.30 configuration. Manned by a crew of 3 (commander, driver, observer) and usually carrying additional stores and ammunitions rather than troops. They were used in Vietnam, some equipped with the Model 74C Cupola/Command Station.

M113A1 MRV
Medium Reconnaissance Vehicle. Similar to the FSV but with a more capable Alvis Scorpion turret with image Intensifier night sight. Amphibious characteristics were enhanced by the fitting of a light sheet metal foam filled trim vane and side pods for extra buoyancy. The drivers hatch was also changed for safety. These were affected generally to Cavalry medium reconnaissance regiments.

Only part of the fleet remains operational order while most were in the late 1980s. Many were converted as utility variants like the M113 Fitter ARV fitted with a HIAB roof crane, but also the modernized M113AS3 and the six-wheeled M113AS4 armed with a Tenix Defence HMG turret.


Belgium replaced its M75 and M59s by a locally-built M113A1-B from 1982 onward. Sub-variants were:

In more recent times, the ADATS Carrier (1988), an air-defence variant was operated within the coalition forces in 1991 gulf war. It was based on the A2 and featured 8 ADATS missile launchers and turret with a X-band radar for tracking. In addition 341 M113A2s were modified under the Armoured Personnel Carrier Life Extension (APCLE) program, 183 of these in the 6-wheeled stretched version. Both have in common a set of upgrades consisting of a 400HP Allison diesel engine, upgraded suspension, bolt-on steel armour plates, steel cage armour, and Cadillac-Gage turret/Nanuk Remote Controlled Weapon Station. These were used in Iraq and Afghanistan until 2013. Some reformed vehicles were converted for civilian uses as tracked log skidders.

Denmark (600+)

50 Danish M113A2 Mk I DK were modified and rebuilt between 1989 to 1993 by E. Falck Schmidt in Odense. Armed with a 25 mm Oerlikon-Contraves autocannon and coaxial 7.62 mm MG03 LMG mounted in an Italian Oto Melara turret and thermal sight. During IFOR/SFOR operation in former Yugoslavia, some received extra add-on armour and spall liner. These were deactivated or reconverted in civilian use in 2009.

Egypt (3000)

Egypt received M113s in the 1980s and locally produced copies known as :
EIFV: M2 Bradley turret, improved armor and engine,
SIFV: 25 mm KBA-B02 turret. upgraded armour resisting 23 mm AP rounds

Germany (4000)

West Germany received hundreds of M113G and M113A1GE later standardized as the A2G which replaced older models and were declined into multiple local variants. The M113A2 EFT GE A0 received an improved SEM-80/90 radio set. and under a modernization program, the MTU engine, new steering and brake systems. The G vehicles receive a bank of eight 76 mm smoke grenade launchers and Rheinmetall MG3s LMGs. The standard APC was known as the Mannschaftstransportwagen.  Variants included :
