Which ATP covers battle drills?

The correct choice pertaining to the coverage of battle drills is ATP 3-21.8, Appendix J. This document specifically addresses individual and collective training on battle drills for infantry units. Battle drills are critical as they are standardized actions that soldiers can perform without detailed commands, ensuring quick and effective responses in combat situations. Appendix J outlines the specific tasks and procedures soldiers must execute as part of these drills, serving as a vital resource for training and operational readiness.

The other options, while important in their respective areas, do not specifically focus on battle drills. ATP 6-22 deals with Army leadership and the development of leadership skills, ATP 3-25.26 focuses on map reading and land navigation, and ATP 3-07 addresses stability operations. Each of these ATPs serves a unique function in military training, but ATP 3-21.8, Appendix J is the authoritative source on the execution and training of battle drills.
