The term Commando mortar refers to a class of lightweight infantry mortars designed for maximum portability and rapid deployment with a caliber of 60mm (2.4 in) or less in diameter, at the expense of accuracy and repeatability. Earliest models had been introduced from the 1930s onwards. Commando mortars often feature design simplifications such as straps instead of bipods, carrying handles, and limited aiming equipment. Some of these straps are marked with measurements, with the intent that the mortarman step on a marked point of the sling and pull it taut, at which point the mortar will be angled so as to fire to the range marked at that point of the sling.
