Which of the following is NOT part of a COA brief?

A Course of Action (COA) brief is an essential part of the Military Decision-Making Process that presents the various COAs to decision-makers and represents critical information about each option. The main goal of this brief is to ensure that the command can assess the feasibility and effectiveness of each proposed COA.

COA statements and sketches provide a visual representation of the proposed actions, helping to clarify what each COA entails. They serve as the foundation of the discussion during the brief, aiding understanding and facilitating decision-making.

Developing broad concepts is also a key component of COA development, as these high-level ideas inform the specifics of the COAs and influence how they are presented during the brief.

Options for enemy engagement fall under the tactical considerations that are critical for evaluating how each COA will interact with and respond to enemy actions, which is integral to understanding the effectiveness of the proposed strategies.

In contrast, the command hierarchy is not typically part of a COA brief. While understanding the command structure is important for overall operations and decision-making, it does not directly pertain to the individual components and assessments presented in a COA brief. Instead, COA briefs focus on the distinct actions proposed for the operation rather than the internal command structure.
