Which TC covers the M4 Carbine?

The correct answer pertains to the field manual that specifically addresses the M4 Carbine and its capabilities, operation, maintenance, and other pertinent information. TC 22.9, known as "TC 3-22.9 Rifle Marksmanship," encompasses the doctrine and procedures for training with the M4 Carbine and includes detailed information about its firing techniques, care, and training strategies.

In addition, this training circular is part of a broader set of documents aimed at improving soldier proficiency in using the M4 Carbine effectively. It serves as a guide for both trainers and soldiers to ensure that all aspects of handling and utilizing the M4 are well covered.

The other options do not specifically cover the M4 Carbine in the same comprehensive manner as TC 22.9. While they may reference various aspects of firearm training or military operations, they don’t focus solely on the M4 Carbine’s features and training requirements. Understanding the specific role of TC 22.9 reinforces why it is aligned with M4 Carbine training standards and essential for effective use in combat scenarios.
