This mortar can be deployed as infantry support for destruction of personnel and enemy firing positions, for opening routes through barbed wire obstacles and mine fields, for demolition of fortified objects, for destructing infrastructure elements, illumination and deploying smoke screen. The M74 model when disassembled could be carried by 3 soldiers thus having unique capabilities regarding transport in area with obstacles or in urban area compared with more heavier mortars.

Since it is very light regarding its caliber it can be easily airdropped and parachuted to firing position. It uses NSB-4B sight for firing.[3] Base-plate of M74 mortar is triangle shaped.
