How is Marine Corps doctrine defined?

• A. A teaching of the fundamental beliefs of the Marine Corps on the subject of war, from its nature and theory to the preparation and conduct
• B. A training manual for rifle ranges
• C. A legal framework for operations
• D. A collection of field manuals

Answer: (A)

Doctrine serves as the Marine Corps’ guiding framework for war. It articulates how the force thinks about war—the nature of warfare, the fundamental theories of strategy and operations—and how Marines should prepare for and execute operations. This makes it broader and more enduring than specific procedures. It is not a rifle-range training manual, which would focus on a single skill; nor a legal framework, which governs rules and constraints; nor a collection of field manuals, which contain task-specific instructions. Doctrine thus describes the overarching approach that shapes planning, training priorities, and decision-making in warfighting, whereas the other options point to specialized documents or rules rather than the enduring worldview and method doctrine provides.
