- ADP 3-13Publication
Information
ADP 3-13 is the Army's first doctrinal publication devoted to information. It explains how Army forces create and exploit information advantages and how information effects are planned and integrated like any other capability. It is newer than most of the doctrine on this list, so expect subordinate publications to still be catching up.
- ADP 3-0Publication
Operations
ADP 3-0 is the Army's capstone description of how it conducts operations. The March 2025 edition carries multidomain operations as the Army's operational concept and supersedes the July 2019 edition. It sets the vocabulary -- warfighting functions, combat power, the operational framework -- that nearly every other doctrinal publication uses.
- FM 3-0Publication
Operations
FM 3-0 is the Army's capstone operations manual: how Army forces contribute landpower to the joint force and integrate joint capabilities on land. The March 2025 edition builds on multidomain operations and focuses on large-scale combat against a peer threat. If you are on a division or corps staff, this is the manual you argue from.
- ADP 3-37Publication
Protection
ADP 3-37 is the Army's primary publication for the protection warfighting function. It explains how commanders preserve combat power through risk management, prioritization, and the protection tasks that get built into every plan. The April 2026 edition supersedes the January 2024 version.
