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.

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.

The Army's operational concept: multidomain operations
Multidomain operations is the Army's operational concept. It replaced unified land operations, which means a lot of study material written before 2025 is teaching a superseded framework.
