It is also operated by other forces. Marines call them “amtracks,” a shortening of their original designation, “amphibious tractor.” It is capable of carrying 25 combat equipped Marines in addition to the crew of 4: driver, crew chief/vehicle commander, gunner, and rear crewman. This vehicle is armed with a M85 .50cal machine gun. Its speed is 15–20 mph off-road, 45 mph on a surfaced road, and 8.2 mph in water.
