Variants of the M113 armored personnel carrier


A huge number of M113 armored personnel carrier variants have been created, ranging from infantry carriers to nuclear missile carriers. The M113 armored personnel carrier has become one of the most prolific armored vehicles of the second half of the 20th century, and continues to serve with armies around the world in many roles.

Military operators

Afghanistan

In 2005, Afghanistan received 15 second-hand M577A2 command and control vehicles from the United States.

Argentina

In 1967, the Argentine Army received from USA 250 M113A1 APC, 10 M577A1 command and control vehicles and 12 M548A1 cargo carriers. In 1992, they received from USA 200 M113A2 APC, 25 M106A1 mortar carrier, 10 M577A1 command and control vehicles and 16 M548A1 cargo carriers. Some variants are modified by the Army's Comando de Arsenales.

    Australia

Some Australian AFVs have the suffix "AS", often appended by a model number.
Generally speaking, Australian models are modified from the original models, in the case of the M113A1 series this included the AN/VIC-1 communications harness, large dust filters for the passenger compartment ventilation blower, heavy steel track manufactured by ADI, provision for 600 kg of belly armor, the Cadillac-Gage T-50 turret mounting twin.30 Brownings or a.30/.50 Brownings machine guns for APC/LRV versions, a traverse bar to prevent the crew commander traversing the turret to the rear over the troop compartment roof hatch with the guns depressed low. For some reason, besides the M577A1 command vehicle, all of versions of the M113A1 had the passenger compartment heaters removed. In the late 1980s, the fleet was issued with German BM8005 image intensifying night vision driving periscopes, which, with the aid of an adaptor, could be fitted to replace the driver's central periscope for night driving. In the early 90s, the fleet was issued with VINSON family cipher equipment, typically a single KY-57 per vehicle. This allowed the command net to be enciphered, but the admin net would normally work en clair.
  • M113A1 Fire Support Vehicle – Full designation Carrier, Fire Support, Full Track M113A1 Saladin Turret was a variant fitted with the turret from the Alvis Saladin armored car. The FSV was introduced into Australian Army units in the mid-1960s following the withdrawal of the Saladins and was armed with a 76 mm gun, a.30 caliber coaxial machine gun and a.30 caliber machine gun mounted on the roof of the vehicle's turret. The M113 was an interim vehicle and was replaced by the M113 Medium Reconnaissance Vehicle in the late 1970s. It was commonly referred to by Royal Australian Armoured Corps crews as the "Beast". M113A1 FSV is still under service by Philippine Army.
  • M113A1 Fitter – Armored recovery vehicle with HIAB crane mounted on the left side of the hull roof along with a counter weight on the opposite side of the roof. The vehicle can be armed with either the L3A4 machine gun, M60 machine gun or a M2HB.50cal machine gun.
  • M113A1 Light Reconnaissance Vehicle/APC – A standard M113A1 with a Cadillac Gage T50 turret as used on the V100/V150 series of armored cars, mounting two Browning machine guns, a.30 caliber and a M2.50 caliber machine gun. While the standard armored personnel carrier version in Australian service is also fitted with the T50 turret, it initially carried only twin.30 caliber machine guns. In later service, the LRV and APC versions both carried the 30/50 combination and the only difference between them was roles. LRVs, which carried a crew of 2 or 3, were used in the sabre troops of the Cavalry regiment and the recon troop of the Armoured regiment. APCs carried a crew of 2 plus several dismounts, either infantry, assault troops, engineers or other troops. In practise, an LRV was also perfectly capable of carrying troops, though in perhaps somewhat more cramped conditions as LRVs often carried additional stores and ammunition and had seats removed and replaced with storage lockers. For a short period of time in Vietnam, the Aircraft Armaments Incorporated Model 74C Cupola/Command Station was used, but it was quickly replaced by the T50. Also used by the New Zealand Army until the M113 was replaced in 2005. The T50 turret was initially fitted with an optical sight, however in later years this was removed and the guns were solely aimed using ranging bursts of 6–10 rounds. The diesel burning heater is removed from the M113A1 – though numerous diggers note that this is not the case with the Australian Army's M577s.
  • M113A1 Medium Reconnaissance Vehicle – Full designation Carrier, Fire Support, Full Track M113A1 Scorpion Turret was an Australian variant similar to the M113 FSV, but using the turret from the FV101 Scorpion light tank, instead of the older turret of the Saladin armoured car, that the FSV had previously used. This turret was equipped with an Image Intensifier sight for the main armament. This II sight was the first effective passive night sight fitted to an Australian AFV, giving the MRVs a night fighting capability exceeding the Leopard AS1 and all other Australian AFVs of the period. Whilst fully amphibious, the MRV was also fitted with a light sheet-metal foam-filled trim vane and side pods. These pods and the trim vane were intended to provide additional flotation and stability on the water; they provided virtually no additional armour protection. Other changes included a modified driver's hatch which pivoted toward the centre-line of the vehicle instead of opening to the rear of the driver's hatch; this feature preventing the open driver's hatch being caught on the traversing turret, as well as the fitting of the British "boiling vessel", an electric vessel for boiling water and heating rations. As indicated by the designation change, the MRVs were roled as reconnaissance vehicles and issued to the Cavalry regiments with each troop equipped with 3 LRV and 2 MRV; whereas the FSVs were originally issued to APC squadrons and used to provide infantry fire support. The MRV replaced the FSV in Australian service. M113A1 MRV served in the Australian Army until 1996.
  • M113AS3 – significantly upgraded M113A1 with new engine, transmission, steering, suspension, brakes and hull protection.
  • M113AS4 – upgraded to the same standard as the AS3, lengthened to fit an additional road wheel station and fitted with a new Tenix Defence designed electronically driven "one man turret" with 12.7mm heavy machine gun and sight.

    Canada

Models in service:
Under the Armoured Personnel Carrier Life Extension program otherwise known as M113LE Project, which was started after the 1994 White Paper on Defence, it was originally planned that 341 Canadian M113A2 series vehicles were to be upgraded under the contract issued in 2000: 183 were to be stretched by 50 cm and fitted with 6 road wheels and a one-piece rubber Band Track as part of the MTVL series upgrade. The remaining 158 vehicles were to be upgraded to M113A3 standards, retaining 5 road wheels. An optional additional order of 61 air defence vehicles either to the MTVL or M113A3 standard of upgrades for both existing M113A2 ADATS and to convert additional APCs for use as ADATS platforms was also considered. The program underwent three reductions including scrapping the optional ADATS update order and it reduced the total number of vehicles down to 254 vehicles, with just 112 MTVL standard and 142 M113A3 standard being produced starting in 2002.
Modifications for the MTVL series and M113A3 series include a more powerful Detroit Diesel 6V-53TIA series Detroit Diesel Electronic Control IV electronic engine, upgraded suspension, additional fuel tanks that were added under the floor of the vehicle increasing the fuel tank capacity to 757 litres, bolt-on steel armour plates, replacement of the previous lever based steering with a steering wheel, the option of mounting steel cage armour, and improved armament consisting of either a Cadillac-Gage 1 metre turret, a Nanuk Remotely Controlled Weapon Station or a FFNW mounting, although some vehicles have been seen using older weapons mounts in place of not having any weapons mounted due to FFNW and not having enough RWS to equip all vehicles at once.
After being upgraded, the family of vehicles later became known by the acronym TLAV or the LAV-T in Canadian Army parlance. While some vehicles were retired as early as a year after being upgraded, the remaining vehicles are now set to be replaced along with the Bison in the coming decade by the ACSV produced by General Dynamics Land Systems-Canada as announced by the Government of Canada on August 4, 2020.
Under the APCLE program, there were a number of variants created, these include:
  • MTVL – Standard APC variant fitted with a Cadillac-Gage 1 metre turret taken from a AVGP Grizzly, armed with a M2HB.50cal machine gun and a C6 GPMG. Also used as a light munitions carrier. The MTVL series could also be fitted with mission specific equipment such as wire cutters mounted above the headlights on the front of the vehicle or Wegmann 76 mm Multi-Purpose Grenade Launcher Tubes on the front of the turret or the front of the hull. A total of 25 of the variant were produced.
  • MTVC – A replacement for the M548 logistical carriers, It is a flatbed variant of the MTVL with fold-down armoured sides and a tailgate. It provides improved carrying capacity and protection over the previous carrier along with a hydraulically operated crane mounted at the rear of the armoured cab, which is able to handle materials with a load capacity of 1,590 kg at a reach of up to 6.3 m. It can be fitted with a FFNW position allowing a RWS to be installed on the vehicle if redistribution is required for operational reasons. Production of the variant for Canadian Forces began in 2002 like the other variants with an order for 53 vehicles but seems to have been cancelled by 2006 with an unknown number produced.
  • MTVE – Military engineering version equipped with a large plough blade on the front, a hydraulically powered auger on the rear driver's side, and hydraulic hoses for use with hydraulic tools opposite the auger.

Models removed from service:
Canada originally adopted and used the M113A1 series of vehicles after the failure of the domestic program for creating an armoured personnel carrier which had culminated in the Bobcat APC. After the cancellation of the Bobcat in late 1963, Canada began looking for an off-the-shelf vehicle to purchase instead and as the Canadian Army had kept themselves updated on American armour developments, including having even trialed some M59 APCs during the mid to late 1950s in parallel to the Bobcats development, they decided to purchase the M113A1 series as it fit the desired roles for use. In 1964 Canada began to procure the M113A1 from the United States with an order for 300 M113A1s, delivered through 1964–1965, with additional orders in 1968 for 300 M113A1s, and in 1971 for 445 M113A1s.
While the vehicles had all initially used the standard American T130 tracks that came with the vehicles, by 1974 a third of the fleet was using the T130E1 tracks as a large scale trial of the new track which was supposed to have a longer service life of around 60% along with better durability but results of these large scale trials were extremely poor, blamed on poor quality materials used as well as forging defects, these factors led to a search for new tracks to replace both the T130 and T130E1 tracks. The search culminated in the Diehl 213B tracks made in the Federal Republic of Germany which were already being used on the West German M113 fleet. Canadian trials with the Diehl 213B tracks proved conclusively that for a slightly higher cost initially over the T130E1, it had a much longer service life, better durability, easier maintenance, and would save money in the long term. In March 1976 the procurement of the Diehl 213B tracks was approved with delivery to forces in Europe taking place during mid-July, forces in Canada during September, and forces on the UN mission in Cyprus during October. Eventually the entire Canadian fleet was using the Diehl tracks, along with the Lynx and later the M113A2 series.
Beginning between 1980 and 1984, Canada began to procure the M113A2 in limited numbers and also slowly began to upgrade older M113A1s to the A2 standard. As of the early 1990s, Canada had a mixed fleet of A1 and A2 series, for which they began to also procure a large number of ACAV protection kits as early as 1992 for use in United Nations peacekeeping missions like UNPROFOR and later NATO intervention in the Balkans, with these kits even seeing limited use in the War in Afghanistan on some M113A3s and MTVLs. The fleet started to be withdrawn from service in the late 1990s starting mainly with older M113A1s and by the mid-2000s, only vehicles upgraded or being upgraded to M113A3 or MTVL standards were still in service.
  • M113A1 – Basic APC version of the A1 series fitted with either a M2HB.50cal machine gun or a C5 GPMG 7.62mm NATO machine gun, American M113 ACAV kits would be fitted onto some M113A1s. During peacekeeping in the Balkans during the 90s, American M113 ACAV kits would be fitted onto some M113A2s, featuring an armoured protection package around the gunner.
  • M113A1 RCL – A modified APC version converted for use as a recoilless rifle carrier that featured both a M40 recoilless rifle mounted on the top of the vehicle and either a M2HB.50cal machine gun or a C5 GPMG 7.62mm NATO machine gun.

  • M113A2 TUA – Canadian version of the NM142 anti-tank vehicle, utilizing the same Norwegian turret designed by Kværner Eureka but built under Licensed production in Canada on a M113A2 chassis. Some of the additional changes include being fitted with external fuel tanks like other vehicles of the A2 series along with mountings on the rear of the turret for two banks of six Wegmann 76 mm Multi-Purpose Grenade Launcher Tubes. To accommodate the addition of the turret, the Commander's cupola and station were repositioned directly behind the engine wall. Later in service during UNPROFOR the vehicles were mounted with an external coaxial C6 GPMG fitted to the side of the right TOW-2 launcher on the turret, allowing it to be aligned with the main sight for use by the gunner and a connection was added to allow the gunner to fire it remotely. The C6 GPMG also had to be modified to feed from the right side of the weapon due to the side mounting on the launcher. A total of 72 vehicles were modified to this variant, being first fielded in 1989.
  • M113A2 EVSEV - Variant of the M113A2 for engineer units. Fitted with a front-mounted dozer blade, hydraulic ground auger and hydraulic power tools. The hydraulic pump and fluid reservoirs were mounted inside the hull necessitating the development of the initial modification for external fuel tanks mounted on each side of the rear ramp using the A2 style of exterior fuel tanks.

  • M113A2 DAREOD – EOD variant of the M113A2 Mk 1 with 265 hp Detroit Diesel engine. This variant is equipped with a 1-man turret, external fuel tanks, additional search lights and Pearson mine-clearing equipment.
  • M113A3 – Basic APC version of the A3 series, featuring external fuel tanks, not to be confused with the Canadian series standard of M113A3s. These along with potentially other A3 series variants were part of a proposed 200 vehicle acquisition overseen by Colonel Romeo Dallaire which saw trials of the vehicle conducted in both the United States and Canada after the release of the 1987 Defence White Paper by then Minister of National Defence Perrin Beatty. The vehicles were meant to equip the Canadian Forces Reserves but after political lobbying and intervention by Diesel Division General Motors Canada and Canadian Government members like Michael Wilson, who was the Minister of Finance at the time, the Land Forces Command of the Canadian Forces instead opted to procure the Bison light armoured vehicle instead.
  • M113A2 25mm – A prototype built on a basic APC variant of the A2 series that was heavily modified as a fire support vehicle, mounted with the addition of a LAV-25 turret in the center of the vehicle. It was trialed with two main armaments during testing; a 25mm M242 chain gun and a 25mm Oerlikon-Contraves autocannon along with a coaxial C6 GPMG 7.62mm NATO machine gun. Only a single prototype was created and tested during 1985 in Europe with the vehicle later being converted back to a regular APC version.
  • M113A2 ADATS is an air-defence vehicle variant, developed collaboratively between Lockheed Martin and Oerlikon Contraves, first fielded by the Canadian Forces in 1988 with 36 vehicles produced. The system features a turret with an eight tube ADATS missile launcher based on a modified M113A2 chassis. On top of the turret is an X-band radar with a range of 25 km. Used solely by the Canadian Forces, the 34 remaining ADATS have been withdrawn from Canadian service as of April 2012, with no planned replacement announced for it since late 2012. The missile was evaluated by the US Army, but not selected for adoption.
