The 4x4 M1117 was built for US military police use. A door with integral vision block and firing port was provided in each side of the vehicle, and a clamshell door was installed in the right rear corner in a simlar layout to the M706. Also like the earlier vehicle, there were roof hatches over the driver's seats, an engine access hatch was installed on the rear of the left side of the vehicle, and a winch was provided in the right bow. A bank of smoke grenade launchers were mounted on each corner on the turret rear. A V-shaped hull helped protect the vehicle against mine blasts. M1117 was protected against overhead attack from a 155mm shell from 15m (49'), its wheels could withstand a mine filled with 12lb (5.4kg) of TNT, and the vehicle could survive 4lb (2kg) of TNT anywhere. Applique ceramic composite armor and spall liners could be fitted that made the vehicle proof against .50cal AP at 250m (820'). The M1117 could carry more passengers after interior modifications.
