Trivia

 * The 5.56mm round is based on the real world 5.56×45mm NATO cartridge. It was developed for the American AR-15 rifle, later the M16 and several variants, during the Vietnam war in the 1950s, derived from the .223 Remington rifle round. The 5.56×45mm round also replaced the 7.62×51mm round's role as NATO's standard rifle cartridge. While it offers higher muzzle velocity, less weight, and less recoil, it also has a much lower muzzle energy and low penetration than the 7.62×51mm NATO.
