The M939 series 5-ton 6x6 truck is a family of United States military logistical transportation trucks which was designed in the late 1980s and has been in service ever since and appears in the singleplayer campaigns of Battlefield: Bad Company and Battlefield: Bad Company 2.
The M939 Truck appears transporting supplies to an unknown location in the Russian Theatre in Battlefield: Bad Company. The convoy is ambushed several times by RussianArtillery and ground forces and Haggard describes that convoy was "having the worst luck".
Similar Trucks were seen in the Caspian Theater at the end of Ghost Town transporting "Scrap Metal" which was actually the Legionnaire's gold. Bravo One Charlie (A.K.A Preston's squad) stole one M939 Truck filled with gold.
The M939 almost always appears as a prop in the singleplayer missions of Battlefield: Bad Company 2 and appears in multiplayer as a props on certain maps. Reaching an M939 is one of the objectives in Cold War, and a fuel-tanker variant can be driven in the level No One Gets Left Behind as the player approaches the helicopter landing pad. This variant can be useful as an explosive on wheels, with luck, can destroy the enemy Mi-24 Hind taking off from the adjacent landing pad. A variant transporting fuel drums can be found driving through the lumberyard in Upriver which is drivable. The M939 Truck is also featured in the first base in the multiplayer version of Cold War on Rush, it spawns as an Attacker vehicle and can be used as a troop transport.
