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
ADP 1 explains what the Army is for: who we serve, where our authority comes from, and what the Army contributes to the joint force. It is written as much for Congress, sister services, and partners as it is for Soldiers. Read it when you need the institutional answer to why the Army exists rather than how it fights.
