M474

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.

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 Comando de Arsenales of Argentine Army.

Some Australian AFVs have the suffix "AS" (the NATO code for Australia), 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 (early service) 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.

The MRV replaced the FSV in Australian service.
