The Marine was the basic infantry unit of World War II and Modern Age. It is upgraded from the Doughboy. It is best to use it along with Machine Guns and other infantry units in battle. It has a Campaign-exclusive equivalent - the German Infantry. The Marine appears to be named after the U.S. Marine Corps. This could explain the Marine's American G.I.-like appearance. In addition, it was carrying a M14 rifle. It can shoot Helicopters but it only takes away one hit point at a time.
