M120 120mm Mortar

The M120 120mm Mortar replaces the M30 4.2 Inch Mortar in motorized infantry units. The M120 is transported on the M1100 Trailer by the M998 High Mobility Multi-Wheeled Vehicle (HMMWV). The M120, like all other US mortars, fires fin-stabilized ammunition from a smooth bore. Although heavy mortars require trucks or tracked mortar carriers to move them, they are still much lighter than field artillery pieces. They outrange light and medium mortars, and their explosive power is much greater.

The M120 Mortar System consists of the following major components:


Max Range 7200 Meters
Min Range200 Meters
Max Rate of Fire 16 rounds/min (first minute)
