TC 3-22.50 covers the M2 and M2A1 heavy barrel caliber .50 machine guns in the ground-mount role. The same principles and techniques apply to mounted weapons as well. The head space and timing are fixed on the M2A1 and it has a different barrel assembly and a few other subtle differences. Most of the book assumes use of the M2A1 with the M205 lightweight tripod. Soldiers using the M2 or the M3 tripod should read their respective technical manuals. TC 3-22.50 has nine chapters and six appendices. Each chapter and appendix builds on the one before. TC 3-22.50 supports (but does not cover) the Army's training strategy for the weapon at the individual level. TC 3-22.50 describes the aiming devices for the M2/M2A1 that enhance the Soldier's target detection and acquisition skills.
