A Lascarbine is designed for use by special operations units and is usually employed by Drop Troopers or scout units of the Imperial Guard. It is light and compact, allowing it to be easily stowed away so that it does not interfere with the carrier's mobility. It has been used by the Tanith First and Only regiment, the regiments of the Elysian Drop Troops, the regiments of the Catachan Jungle Fighters and Inquisitor Gregor Eisenhorn.
