Which document defines the principles of infantry platoon operations?

The principles of infantry platoon operations are articulated within Army Doctrine Publication (ADP) 3-0, which establishes the overarching doctrine for conducting operations, and further detailed in Army Training Publication (ATP) 3-21.8, which focuses specifically on infantry platoon and squad operations.

ADP 3-0 provides the foundational concepts and principles of operations that apply across various levels of military engagement, while ATP 3-21.8 complements this by laying out the specific procedures, tactics, techniques, and standards for infantry units. The integration of these two documents ensures that infantry platoons have clear guidance on how to operate effectively in alignment with the Army's overall operational doctrine.

Together, ADP 3-0 and ATP 3-21.8 create a comprehensive framework that not only defines the principles of infantry operations but also provides practical applications for those principles in the field, enhancing the effectiveness of infantry units during training and combat scenarios.
