MI Basic Officer Leader Course 2026 Pre-Deployment Practice Test

Military doctrine comes in four forms to cover how forces coordinate at different levels of cooperation: across all services, with allied nations, between multiple services, and within a single service.

Joint doctrine applies universally to all services when they operate together, ensuring a common framework and language. Service doctrine is the specific approach of one branch, like Army, Navy, Air Force, or Marine Corps, tailored to its unique capabilities and processes. Multi-service doctrine sits between joint and service, providing a shared approach for two or more services without full joint integration. Multinational doctrine governs cooperation with allied partners, reflecting how foreign forces and international standards are integrated into planning and operations.

The other options mix concepts that aren’t recognized as the four doctrine types. One option replaces multi-service with force, which isn’t a standard category, and another lists administrative, tactical, operational, and strategic, which are levels of war rather than doctrine types.
