What document outlines the roles and responsibilities of enlisted personnel in the U.S. Armed Forces?

The correct answer is the Army Regulation Handbook, which serves as a comprehensive resource detailing the specific roles and responsibilities of enlisted personnel within the Army. This handbook is essential for understanding the expectations, duties, and protocols that govern enlisted ranks. It provides context for various operational scenarios and lays out the standards of conduct that enlisted members must uphold.

While the Uniform Code of Military Justice establishes the legal framework for military law and discipline, it does not specifically outline the roles and responsibilities unique to enlisted personnel. The Unified Facilities Criteria focuses on facilities and infrastructure rather than personnel guidance. The Department of Defense Directive provides broad policies and instructions but does not delve into the detailed responsibilities of enlisted members like the Army Regulation Handbook does. Therefore, the Army Regulation Handbook is the most pertinent document for understanding the roles and responsibilities of enlisted personnel in the U.S. Armed Forces.
