Which publication outlines safety protocols for military vehicle operations?

The correct choice is based on the specific focus of TC 21-305-20, which is dedicated to the operation and safety of military vehicles. This training circular provides comprehensive guidance on the safe handling, operation, and maintenance of tactical wheeled vehicles, emphasizing risk management, safety protocols, and operational procedures necessary to ensure the safety of personnel during military vehicle operations.

TC 21-305-20 stands out as the authoritative source that outlines the best practices and protocols to mitigate hazards associated with military driving. It serves as a crucial resource for ensuring that military personnel receive the necessary training and knowledge to operate vehicles safely in various environments.

In contrast, the other publications listed have different scopes: AR 600-55 focuses on the Army Driver and Operator Standardization Program, which emphasizes licensing and training requirements but does not detail the specific vehicle operation protocols. FM 21-60 is oriented towards Army physical training and does not address vehicle safety. ATP 4-11 covers sustainment operations and may mention vehicles in a broader logistical context but does not specifically serve as a guide for vehicle operation safety protocols.

Thus, TC 21-305-20 is the most relevant publication specifically outlining safety protocols for military vehicle operations.
