A breech is an opening in a gun where bullets are loaded. If you find yourself in a gun battle with a zombie army, remember that the breech is in the rear of the gun's barrel. Now load up!
Guns or rifles can either be loaded from the back part — called the breech — or from the front — called the muzzle. Most modern guns are loaded from the breech end. And if you’re single-handedly fighting a zombie army, you’d better hope your weapon is breech-loading: it’s much safer and faster to load a gun from the breech.
