The LAV-25 was based on the 8-wheel version of the MOWAG Piranha. Initially, both the Army and Marine Corps anticipated using the vehicle, but Congress cancelled appropriations for the program, and the Marines alone secured funds for the vehicle. Power was able to be sent to all 8 or the rear 4 wheels, and water propulsion was via two propellers at the rear of the hull. A 15,000lb (6800kg) winch was mounted in the left-front hull. The passenger compartment could accomodate six passengers (although four scouts are normally carried), and there were two doors in the hull rear and two hatches in the hull roof behind the turret. When the rear roof hatches are open, sensors prevent the M242 and coaxial machine gun from firing to the rear. The base armor is proof against 7.62mm ball and artillery fragments, and applique armor can be added to proof the vehicle against 14.5mm ammunition.
