refimprove date February 2009 Commando mortar refers to a class of infantry light mortars designed for maximum portability and rapid deployment, at the expense of accuracy and repeatability. Commando mortars often feature design simplifications such as straps instead of bipods, carrying handles, and limited aiming equipment. Some commando mortar straps are marked with measurements, with the intent that the mortarman step on a marked point of the sling and pull the sling taut, at which point the mortar will be angled so as to fire to the range marked at that point of the sling.
