The G11 is a firearm created by Heckler & Koch. It is sometimes used as a slang to "sleep" due to a character of the same name from "Girls' Frontline," who is known for always being sleepy.
A revolutionary weapon designed by Heckler & Koch in the 1980's for the West German military, the G11 is the most famous weapon to utilize caseless ammunition. Instead of the traditional method of placing gunpowder inside a brass casing, and then placing the bullet itself on top, H&K created a cartridge where the powder charge is simply formed into one solid block behind the bullet. The lack of a casing eliminates the extraction phase of operations, there by allowing the G11 to achieve rates of fire of 2000 rounds per minute on burst mode.
