M-4 commando mortar explained
The M-4 commando mortar, also known as a patrol mortar, is a lightweight 60 mm commando mortar manufactured by Denel Land Systems.[1]
Description
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]
Ammunition
It uses the M-61 series of bombs in high explosive, smoke, illumination and practice versions.
Variants
- M4: pulling a lanyard releases the firing mechanism
- M4 Mk 1: equipped with a fixed firing pin
- M4L3: version with simplified baseplate and sight, range is shorter (1,200 m).
