This general type of document is the body of thought on how we fight in present to near term with current force structure and materiel. Field Manual (FM) 3-0, Operations, is the keystone manual, normally relevant immediately 3-5 years. It includes fundamental principles, tactics, techniques, procedures, terms and symbols that the force can apply. It is authoritative, in that it must be synchronized with joint doctrine.

• A. Realignment
• B. Concept
• C. Reprogramming
• D. Doctrine

Answer: (D)

Doctrine is the guiding framework that describes how we fight now and in the near term, using the current force structure and materiel. Field Manual 3-0, Operations, serves as the keystone of that doctrine, providing the fundamental principles, tactics, techniques, procedures, terms, and symbols the force applies. Its authority comes from being synchronized with joint doctrine, ensuring a consistent approach across services. Realignment focuses on moving resources rather than prescribing how operations are conducted; a concept is too broad and not the codified guidance that directs action; reprogramming deals with budgetary changes rather than battle-tested guidance.
