60MM Mortar/81MM Mortar
Marines are known for their exceptional ability to work cohesively as a unit, and nowhere is this more evident than when mortar teams are providing effective, indirect fire on a target. With 60mm and 81mm mortars, Marines work together to provide constant and accurate high-angle suppressive fire on targets they may not be able to even see. Marine mortar teams locate targets by converting chart data to firing data, delivering mortar fire in timely response to the ground units they support.
Serving as lightweight, portable artillery, mortars are fired by dropping each round into the muzzle. The round slides down the base of the barrel where it strikes the firing pin located inside the base cap. The flame from the exploding cartridge ignites the propelling charge, producing the gas pressure that drives the round up and out of the barrel, high into the air. After it has reached its apogee, the mortar round falls to the target.

60mm mortars are organic to the rifle company and have a range of 3500 meters. 81mm mortars are an asset of the infantry battalion and have a range of 5700 meters. Both mortars can fire:
High Explosive (HE) shells (several varieties) – Effective against lightly armored targets, personnel and fortifications
Smoke rounds – Effective as a screening or signaling round
Illumination rounds – Effective in night missions requiring illumination of an enemy target
60mm and 81mm Mortars
With 60 mm and 81 mm mortars, Marines work together to provide constant and accurate high-angle suppressive fire. Marine mortar teams must interpret calls for fire from a forward observer in order to locate their targets on a map and then convert that data into a firing solution for their mortars.
