Which step involves a detailed assessment of each COA in respect to the adversary?

The step that involves a detailed assessment of each Course of Action (COA) in relation to the adversary is Course of Action Analysis, commonly referred to as wargaming. During this phase, planners simulate how each COA will perform against the anticipated actions and reactions of the adversary. This process helps to identify potential strengths and weaknesses of each COA, ultimately guiding decision-makers toward selecting the most effective course for the mission.

Wargaming allows for an in-depth consideration of various scenarios and outcomes—this consideration is critical as it provides insights into how adversaries might respond to different tactics and strategies. This step is distinct from Course of Action Comparison, which is more focused on evaluating the merits of the COAs against established criteria, rather than specifically against adversary actions.

Transition refers to moving from planning to execution, which does not entail assessing COAs against adversary actions, while Mission Analysis is concerned with understanding the operational environment, mission objectives, and constraints, rather than evaluating the effectiveness of COAs against adversarial responses.
