Designed to fix the shortcomings of the 105mm M27 that preceded it, the M40 was light and powerful, and added a .50 caliber spotting rifle to assist in being able to make first-round hits. The massive backlist of a recoilless rifle dictates that a crew generally only has one chance to make a hit before they must relocate to avoid retaliatory fire.
