What concept enables units to act independently, yet with unity of purpose?

• A. Centralized planning and Decentralized execution
• B. Unified Command
• C. Parallel Command
• D. Decentralized Planning and Centralized Execution

Answer: (A)

Centralized planning and decentralized execution works because a single plan defines the mission, end state, and limits, while allowing units at lower levels to carry out the work autonomously in the field. The higher echelon sets the overall intent and objectives, then pushes decision-making authority to those closest to the action. This enables quick, locally informed actions that adapt to terrain, enemy movements, or changing conditions, yet everything remains aligned with the same overall purpose.

This approach maintains unity of effort because every unit understands the desired outcome and the constraints within which they must operate. They don’t need to wait for new orders for every action; instead, they exercise initiative to achieve the plan’s aims, ensuring actions across the force stay coordinated toward the shared end state.

The other options aren’t as fitting because they describe different structures. Unified Command involves cross-agency authority sharing for a joint effort, not the specific planning-to-execution flow. Parallel Command implies multiple independent commands working side by side without a single, guiding plan, which can fragment efforts. Decentralized Planning with Centralized Execution reverses the flow, placing planning decisions at lower levels but keeping execution centralized, which can slow responses and reduce adaptability.
