The GL-4 Grenade Launcher is a simple light tubular launcher capable of firing most grenade types with a compressed gas or electromagnetic charge. While grenade launchers can carry and fire most of the more commonly available grenade types, they are almost universally loaded with concussion or anti-tank grenades. Confederate GL-4 grenade launchers use drums with 10 pre-loaded grenades, though users can reload the drums with other types of grenades, if necessary.
