Features: The M224 60mm Lightweight Mortar is a smooth bore, muzzle loading, high-angle-of-fire weapon. The cannon assembly is composed of the barrel, combination base cap, and firing mechanism. The mount consists of a bipod and a base plate which is provided with screw type elevating and traversing mechanisms to elevate/traverse the mortar. The M64 sight unit is attached to the bipod mount via a standard dovetail. An additional short range sight is attached to the base of the cannon tube for firing the mortar on the move and during assaults. It has a spring-type shock absorber to absorb the shock of recoil in firing.
Background: The M224 replaced the older (WWII era) M2 and M19, 60mm Mortars. These weapons only possessed 2,200 yards of effective range. The M224 was designed to fire all types of the older ammunition, but its primary rounds are of the newer, longer-range type.
