The M249, a key infantry automatic weapon, is detailed in FM 3-22.68. This field manual provides comprehensive guidance on the operation, maintenance, tactics, and techniques associated with the M249 machine gun. It serves as an essential resource for soldiers needing to understand the weapon's capabilities, employment, and best practices for ensuring effective use in various combat situations.

Choosing FM 3-22.68 aligns with the Army's focus on ensuring soldiers are well equipped with the knowledge required for effective use of individual and crew-served weapons. This includes instructions on loading, firing, and clearing malfunctions, as well as combat and gunnery scenarios specific to the M249.

The focus of the other manuals does not specifically address the M249 in the same detailed manner, which is why FM 3-22.68 is recognized as the authoritative source for this particular weapon system.
