The Heckler & Koch G11 is a non-production prototype assault rifle developed during the 1970s and 1980s by Gesellschaft für Hülsenlose Gewehrsysteme "Corporation for Caseless Rifle Systems", a conglomeration of companies headed by firearm manufacturer Heckler & Koch (mechanical engineering and weapon design), Dynamit Nobel (propellant composition and projectile design), and Hensoldt Wetzlar (target identification and optic systems). The rifle is noted for its use of caseless ammunition. It was primarily used for self defence by Rikhart Harken, a mercenary ace pilot, due to its compact design.
