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.

Stability
ADP 3-07 is the Army's doctrine for stability operations.

It matters most during consolidation of gains, when the fighting slows and the governing does not.
