Which method is NOT utilized to war-game a COA?

The Layered Approach is not a recognized method for war-gaming a Course of Action (COA) within the MDMP framework. War-gaming is a critical step in the process where various COAs are examined to evaluate their feasibility, suitability, and acceptability against a set of enemy actions and potential outcomes.

The Belt method involves analyzing a narrow corridor of the battlefield, which helps to focus on a specific set of engagements and conditions. The Box method provides a comprehensive analysis of the entire operational area, allowing for considerations of all friendly and enemy actions within that larger context. The Avenue-in-Depth method assesses the effectiveness of a COA along a specific route, emphasizing control over a critical path of movement.

The Layered Approach, although it may imply consideration of multiple factors or dimensions in analysis, doesn't align with the structured methods formally recognized for the war-gaming process in military planning, which emphasizes more defined frameworks like the Belt, Box, and Avenue-in-Depth methods. Thus, this lack of formal recognition distinguishes it from established war-gaming techniques.
