Which of the following are types of COA analysis methods?

• A. Box
• B. All of the above
• C. Avenue in depth
• D. Belt

Answer: (D)

COA analysis methods organize how we test courses of action by examining how they unfold in time and space. The belt method analyzes an operation as a series of connected bands or belts, each representing a sector, axis, or phase where actions are coordinated to achieve the overall objective. This approach highlights how fires, maneuver, and sustainment synchronize across adjacent belts, and it makes visible timing dependencies, potential bottlenecks, and gaps between sectors. By tracing the action along each belt, you can assess feasibility, risk, and the need for adjustments to maintain alignment with the commander’s intent. In this framework, the belt concept uniquely focuses on linear coordination and sequential or parallel action across zones, which is why it best fits the question. The other terms listed aren’t standard COA analysis methods in this context, so they don’t provide the same analytical structure for evaluating how a COA unfolds across the battlefield.
