Mortars are 'The infantry's artillery', providing artillery-like fire support to small infantry units when artillery is either not available, or cannot be moved forward fast enough. In the U.S. Military, the typical deployment is that light 60 mm mortars are at the platoon or company level, supported by 81 mm mortars at battalion, and by the 4.2 inch mortars (now 120 mm) at regimental level.

Charactaristics of Mortars
A mortar is an indirect fire weapon that consists of a tube into which a mortar shell is dropped. The shell hits bottom on a fixed firing pin, setting off a detonation which propels the shell out with a high ballistic trajectory. Mortar rounds have fins to stabilize their flight and cause the shell to strike fuze-end first.
Since before World War II, mortars have had these components:
Light (60 mm) and medium (81 mm) mortars are portable, carried into combat by their crew. Heavy mortars are installed in custom gun carriages and are employed like artillery.
Mortars are used for battlefield illumination at night, to lay down smoke to conceal troop movements, and for anti-personnel fire using high explosive rounds. Chemical mortars have been used in the past but are not now part of the U.S. inventory.
