M120 120 mm mortar
From Wikipedia, the free encyclopedia
The M120 120 mm mortar replaced the M30 107 mm (4.2 inch) mortar in United States Army motorized infantry units. The M120 is transported on the M1100 Trailer by the M998 High Mobility Multipurpose 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 entered service with the United States Army in 1991. Its mission is to provide heavy weapon, high-angle organic indirect fire support to the unit commander. The m120 is used by both mechanized units as well as light infantry in certain situations. The m120 has 2 bipods, one is for mounting inside of LMTV's and the other bipod is for strictly ground deployed use.
