For modern day warplanners, it remains a running challenge to arm the common infantryman with a useful indirect Line-of-Sight (LoS) weapon. Hirtenberger of Austria markets its M6C "Commando" mortar for such a role, being lightweight and requiring very little setup before entering combat. The system is of 60mm caliber and weighs a handy 6.4 kilograms allowing the mortar to fit inside of a backpack or slung over the shoulder. The product is available in a variety of finishes and supports day, night and IR visible sighting devices.
Aiming for the weapon is achieved through the HDS aiming device which promises a great degree of accuracy at range. The arrangement allows the operator to address elevation requirements through a fast and easy process and is also protected against the elements. An built-in LED illumination feature is powered internally by way of a battery. Steel is featured in the construction of the barrel assembly and is rated to a Charge 3 tolerance. A cover is provided at the front end of this assembly to protect the firer's hand from burns in the heat-of-battle. Two types of base plates are made available to the operator - one designed for soft terrain and another for hard terrain. The latter incorporates a steel spike into its design. To facilitate their switching, the M6C-640 has a tool-less "quick-change" feature that allows the operator to make the change in about 10 seconds.
There are several forms available in the M6C family line: Mk 2, the Mk 2-s and "Commando". Each differs primarily in their listed engagement ranges with the Mk 2 reported at 1,920 meters, the Mk 2-s at 2,010 meters and the Commando at 2,360 meters. Overall length of all types is 840mm with a barrel launch tube measuring 640mm.
The M6C is cleared to fire the gamut of mortar bombs / projectiles in service across the globe. Operators include Austria, Bulgaria, Georgia, Greece, Italy, Switzerland and Japan.
