Defense Support of Civil Authorities

ADP 3-28 explains how Army forces support civil authorities at home -- disaster response, civil support, and the legal boundaries that come with domestic operations. It covers both the federal force and National Guard civil support missions. Read it before a hurricane rotation, not during one.

Offense and Defense

ADP 3-90 holds the fundamentals of offensive and defensive operations: the forms of maneuver, the types of attacks, and the forms of the defense. It is the doctrinal parent for FM 3-90, Tactics, which carries the detail. If a board asks about the four types of offensive operations, this is where the answer lives.

Fires

ADP 3-19 defines the fires warfighting function -- its tasks, its capabilities, and how effects are delivered and integrated through targeting. It deliberately covers more than field artillery: air and missile defense, joint fires, and nonlethal effects all live here. It replaced ADP 3-09 as the Army's fundamental fires publication.

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.

Stability

ADP 3-07 is the Army's doctrine for stability operations. It explains the stability operations tasks, how they relate to offense and defense, and how military efforts fit alongside civilian agencies and host-nation institutions. It matters most during consolidation of gains, when the fighting slows and the governing does not.

Tactics

FM 3-90 is the Army's tactics manual for offensive, defensive, and enabling operations. It merged the two 2013 volumes of FM 3-90 into one book, so reconnaissance, security, and other enabling tasks now sit with the offense and defense chapters. It is the detail behind ADP 3-90.
