Which of the following best describes COA statements?

The correct choice accurately identifies that COA (Course of Action) statements are detailed operational plans outlining how a unit will accomplish a specific mission or objective. These statements provide a comprehensive overview of the tactical and strategic elements required to execute the plan effectively, including resources, timelines, and the various phases of action.

Detailed operational plans encapsulate all critical aspects of the proposed course of action, allowing leaders to evaluate viability, feasibility, and acceptability. This depth of detail ensures that all participants in the planning process clearly understand how to proceed and what is expected, making it an essential component of military planning and decision-making processes.

The other options do not fully capture the nature of COA statements. General observations may provide insights but lack the structured and detailed approach found in COA statements. Summary reports typically synthesize information rather than present actionable plans. Lastly, the commander's intent conveys broader objectives and guidance but does not delve into the specifics required for operational planning, which is the essence of COA statements.
