Small arms
Small arms master gunner (SAMG) is an appointment of a subject matter expert in the field of small arms, optics, and lasers for combat units. Not all units have SAMGs. Units which understand that the knowledge of operating a weapon in conjunction with the myriad assortment of optics and lasers to their fullest extent employ SAMGs to help keep their operators current on these devices. Having a "go-to-guy" at the division, brigade, and battalion levels, who can supply the correct off-sets for bore-lighting the lasers, and who not only understands, but can teach how, to zero the optics correctly is an invaluable commodity in the combat arms arena.
