An M40 recoilless rifle on its M79 "wheelbarrow" tripod Diagram of the operation of a recoilless rifle using a vented case. A recoilless rifle (), recoilless launcher (), or simply recoilless gun, sometimes abbreviated to "RR" or "RCL" (for ReCoilLess) [1] is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant ...
Taking the M27 as the basis for a new design, the Army developed an improved version of the M27 that was type-designated the M40 106-mm recoilless rifle in 1955. [22] Although unsuitable for military purposes, M27 recoilless rifles were used to trigger controlled avalanches at ski resorts and mountain passes in the United States. [23]
The M18 recoilless rifle is a 57 mm shoulder-fired, anti-tank recoilless rifle that was used by the U.S. Army in World War II and the Korean War. Recoilless rifles are capable of firing artillery -type shells at reduced velocities comparable to those of standard cannons, and almost entirely without recoil .
Technically, only devices that use a rifled barrel are recoilless rifles. The smoothbore variants (those devoid of rifling) are termed recoilless guns. This distinction is often lost, and both are often called recoilless rifles. Normally used for anti-tank roles, the first effective system of this kind was developed during World War II to ...
The M67 was issued in response to a demand for a reloadable shoulder-fired weapon to be used in static defensive positions as well as ambushes. In particular, the flechette anti-personnel round saw common usage. [9] The M67s were eventually phased out again as the Army expanded issuing of the M3 Carl Gustav recoilless rifle to regular infantry ...

During the Vietnam War 105 mm howitzer batteries and tanks (90 mm guns) used flechette rounds to defend themselves against massed infantry attacks. The ubiquitous 105 mm M40 recoilless rifle was primarily used as an anti-tank weapon. However, it could also be used in an anti-personnel role with the use of
This distinction is often lost, and both are often called recoilless rifles. [4] Though similar to a rocket launcher, a recoilless weapon fires shells that use conventional gun propellant. The key difference from rocket launchers (whether man-portable or not) is that the projectile of the recoilless rifle is initially launched using ...
