FMTV A2 (Family of Medium Tactical Vehicles)

The Family of Medium Tactical Vehicles (FMTV) is the US Army's standard 4x4/6x6 medium tactical truck family, derived from the Austrian Steyr 12M18 chassis and built to US Army requirements including a minimum 50 percent US content. Manufacturing passed from Stewart & Stevenson to Armor Holdings to BAE Systems before Oshkosh Corporation won the rebuy competition and has produced the current A2 generation since 2011; Oshkosh Defense's own FMTV product page confirms it as the current manufacturer. Roughly 74,000 trucks and trailers were built by the earlier manufacturers and BAE Systems, with Oshkosh Defense adding over 40,500 more as of August 2021 with production continuing. The family spans 17-plus variants split between the 2.5-ton Light Medium Tactical Vehicle (LMTV, e.g. M1078 cargo) and 5-ton Medium Tactical Vehicle (MTV, e.g. M1083 cargo) classes, plus specialised dump, tanker, wrecker, van and HIMARS-launcher-chassis variants. This record documents the baseline M1083A1P2 5-ton MTV cargo truck: 11,280 kg curb weight with fuel, 4,535 kg (5 US ton) rated payload, powered by a Caterpillar C7 7.2-liter 6-cylinder diesel producing 330 hp through an Allison 3700 SP 7-speed automatic transmission, with a 483 km range and 94 km/h top speed. FMTV is a distinct, lighter product family from the existing HEMTT M977 record (8x8, roughly 31 t combat weight): FMTV covers the Army's 2.5 to 10 US ton medium-truck class, while HEMTT covers the heavier 8x8 class, and Wikipedia's own FMTV article treats HEMTT only as a related heavier platform, not a sibling variant.
