Notes: This is an El Salvadoran light APC built on the chassis of the old M-37B1 3/4-ton truck of World War II vintage. The vehicles were assembled in El Salvador using existing M-37B1 trucks and kits imported from the US. The vehicles had armor add-on panels added, as well as mesh to pre-detonate HEAT warheads, such as the RPG-2 and RPG-7 which are so common in Latin America. This primitive spaced armor stops only one extra die of damage instead of two dice. Kevlar blankets are added inside this armor. The driver and commander have an armored door, with bullet-resistant glass; the windscreen is also made of bullet-resistant glass, and in the frame on the commander’s side is a firing port.

Two versions of this vehicle exist. The first is troop carrier; these vehicles have no armament. The second type is the weapons carrier; these vehicles have a one-man armored cupola directly to the rear of the driver and commander with twin M-2HBs, and an M-60 machinegun with an AV2 gun shield on either side of the troop compartment. Recent upgrades have improved off-road performance.
