M120 is a U.S. 120 mm smoothbore mortar based on the Israeli Soltam K6 design.
The M120 is the U.S. Army's 120 mm mortar system, derived from the Soltam K6. FAS describes it as a smoothbore mortar firing fin-stabilized ammunition, while Military Factory identifies it as the Israeli Soltam K6 in U.S. service. The mortar-system category is appropriate.
The system provides greater range and explosive effect than 60 mm or 81 mm mortars, usually with vehicle transport or towing.
M120 offers heavy indirect fire at battalion level. The 120 mm bomb gives stronger effects against troops, field positions, and light structures, while the smoothbore tube and baseplate system remain simpler than field artillery. Its weight means it is less portable than smaller mortars and often depends on vehicles.
M120 matters because heavy mortars provide responsive fire without the full footprint of artillery batteries.
The system can deliver smoke, illumination, and high-explosive fire quickly for maneuver units. Its effectiveness depends on fire direction, ammunition supply, crew skill, and rapid displacement under counter-fire threat. It remains a practical middle ground between light mortars and howitzers.
