Which reference covers the M4 carbine?

• A. AR 165-1
• B. FM 3-22.9
• C. FM 1-05
• D. AR 670-1

Answer: (B)

The weapon’s official guidance is found in a field manual that focuses on how to shoot and train with rifles, including the M4 family. The manual that covers rifle marksmanship for the M4 carbine—its handling, firing fundamentals, zeroing, and maintenance—is Field Manual 3-22.9, Rifle Marksmanship. This document lays out the step-by-step techniques, standards, and procedures soldiers use to train and qualify with the M4.

Other references are oriented toward different topics: Army Regulations typically address policies, procedures, or standards (such as uniforms or administrative rules) rather than hands-on weapon training. As a result, they don’t provide the rifle-specific guidance found in the rifle marksmanship manual.
