The M-4 commando mortar, also known as a patrol mortar, is a lightweight 60 mm commando mortar manufactured by Denel Land Systems. [1]
As with other mortars of this type it is intended for rapid use over short ranges as a fire support weapon. It has a lanyard operated trigger mechanism in the breech which allows it to be carried loaded with a bomb, unlike other mortars that have fixed firing pins. The lack of a bipod means it is not as accurate as a conventional mortar and is unsuitable for sustained fire use. The sighting system incorporated in the handle consists of a pair of curved spirit levels one to indicate that it upright in the lateral plane and the other indicates the range with a charge table. Beta lights illuminate the sight for night use. [2]
It uses the M-61 series of bombs in high explosive, smoke, illumination and practice versions. [2]

A grenade launcher is a weapon that fires a specially designed, large-caliber projectile, often with an explosive, smoke, or gas warhead.

The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organization by military forces.
A mortar today is usually a simple, lightweight, man-portable, muzzle-loaded cannon, consisting of a smooth-bore metal tube fixed to a base plate with a lightweight bipod mount and a sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy siege artillery. Mortars launch explosive shells in high-arching ballistic trajectories.
