What FM document covers the M249?

The correct answer is rooted in the designation of the Field Manual (FM) that specifically addresses the M249 Automatic Rifle, which is an integral part of the U.S. Army's infantry weapon system. FM 3-22.68 is dedicated to the M249, providing comprehensive guidance on its operation, maintenance, and training aspects. This manual encompasses crucial information on the weapon's characteristics, capabilities, and procedures, essential for effective use in both training and combat scenarios.

Understanding such manuals is vital for Non-Commissioned Officers (NCOs) as it supports their knowledge of weapons systems critical to their unit's mission. Familiarity with FM 3-22.68 ensures that NCOs can adequately instruct Soldiers on proper handling, firing techniques, and maintenance requirements of the M249, thereby enhancing unit readiness and effectiveness in the field.
