G11

The Heckler & Koch G11 is a prototype assault rifle developed during the 1970s and 1980s. It is noted for its use of Caseless ammunition.

Overview
During the Peace Walker Incident, Big Boss and his mercenary group, the Militaires Sans Frontieres, procured some design specs for the G11 after a successful stealth run through the United States Missile Base in Nicaragua.

Post-Peace Walker
By the 1990s, the G11 had finished development intended for the Bundeswehr and other NATO partners. However, despite the fact that it was technically a success, it was cancelled due to it lacking a patent as well as the events of the Reunification of Germany.

In-game weapons description
"A prototype assault rifle currently in development as the next generation of infantry weapon. It uses a newly developed "caseless" ammunition whose rounds do not require a metal case. The new ammo maks the G11 increadibly easy to control due to its extremely low recoil. The downside to this is that the bullets themselves are not that powerful. Thus, the key to using the G11 is carefully aiming shots to ensure they hit their intended targets. The G11's snag-free style allows it to be equipped without reducing the camo index significantly, making it well-suited to sneaking missions."
