The mortar can be fired in the conventional mode or handheld mode. It can be drop-fired or trigger-fired.

The inherent limitations of a light mortar (short-range and small-explosive charge) can be minimized by careful planning and a thorough knowledge of its capabilities. The M224 can be employed in several different configurations. The lightest weighs about 18 pounds; the heaviest weighs about 45 pounds. Each round weighs about 4 pounds. The mortar can be fired accurately with or without a fire direction center.
