M6 Mortar

The M6 mortar family was developed by Hirtenberger Defence Systems as a compact 60 mm mortar system for infantry units needing portable indirect fire. British Army use is associated with urgent operational requirements from Afghanistan, where small units needed a lighter weapon than 81 mm mortars while retaining useful range and explosive effect.

Technically, the M6 is a muzzle-loaded 60 mm smoothbore mortar available in different barrel lengths and configurations. It can be fired in a more complete bipod-mounted role for accuracy or in lighter commando-style configurations for mobility. The system's value comes from a low carried weight, simple manual operation, and enough range to support small-unit maneuver.

Operationally, 60 mm mortars such as the M6 are useful for patrol bases, dismounted operations, and terrain where heavier support weapons are difficult to move. They provide quick suppression, smoke, and illumination under local control. The British experience in Afghanistan highlighted why light mortars remain relevant even when precision artillery and air support are available.
