The Field Manual for the M136 AT4 is FM 3-23.25. This manual provides comprehensive guidance on the operation, maintenance, and employment of the AT4 antitank weapon system. It addresses vital procedures for its use in various combat scenarios, ensuring soldiers understand how to effectively utilize this weapon on the battlefield. The field manual includes information on safety protocols, firing techniques, and tactical considerations, which are essential for maximizing the weapon's effectiveness in combat.

The other field manuals listed pertain to different weapons systems or topics—such as FM 3-22.68, which deals with the LAW (Light Anti-tank Weapon); FM 3-22.9, which covers the M9 pistol; and FM 4-25.11, which focuses on first aid practices. Each of these documents serves a specific purpose in training and operational planning, but none provides the relevant information for the AT4 like FM 3-23.25 does.
