This manual, “Crew-Served Machine Guns: 5.56—and 7.62 mm (FM 3-22.68),” provides a single source of technical information, training techniques, guidance for using, and integration into combat operations of three crew-served machine guns, the 5.56-mm and 7.62-mm M60, M240B, and M249. For quick reference, this publication includes an appendix with all of the firing tables collocated. Trainers must ensure that everyone observes safety procedures at all times. Leaders, trainers, and Soldiers must remember: safety is everyone’s full-time responsibility. They must conduct all training as though each weapon is fully loaded. In training, safety is always more important than speed or accuracy.
