|Zil-131 Army Truck|
The ZIL-131 is a general purpose 3.5 tons 6x6 army truck, the basic model being a general cargo truck. Variants include a tractor-trailer truck, a dump truck, a fuel truck, and a 6x6 for towing a 4-wheeled powered trailer. The ZIL-131 also serves as a platform for the BM-51 "Prima" rocket launcher, a 50-tube variant of the BM-21 "Grad".
The ZIL-131 is part of a family of two trucks sharing identical components by ZIL, which also included the ZIL-130 Truck. Both trucks were introduced in 1967. The ZIL-131 6x6 has the same equipment as the GAZ-66 and Ural-375D. Unlike the ZIL-131, the ZIL-130 is intended for civilian use.
