In Red Dragons, the MD Jupiter is an West Germany 5 point APC (in-game category, but commonly refered to as a truck) that is available to infantry units in the Logistics and Recon tab.
Trucks have excellent fuel economy and are wheeled, giving them the best on-road speed possible, and typically have passable offroad speed as well. With their price being so low, they lend themselves to the cost-efficiency of the units they carry, keeping the price-point for even high-tier recon units at a more acceptable level. Their low price also makes them good for prodding enemy defenses. However, despite their benefits, trucks also come with a number of issues: most notably, they are limited to infantry CVs and recon units, limiting their usefulness quite significantly. Additionally, any anti-tank weapons can instakill a truck and whatever infantry they're carrying (even low-tier anti-tank weapons such as the M72 LAW can kill a truck with a 15-man team in them, and bombs and artillery can also easily destroy them). Almost all of them are unarmed, as well, making them useless during actual fighting.
