Which of the following is NOT one of the five phases of the military decision-making process (MDMP)?

The military decision-making process (MDMP) consists of a series of systematic steps that aid military leaders in developing effective plans. The correct option that is not part of the MDMP is Deployment Planning.

Deployment Planning generally refers to the logistics and execution of moving troops and resources to a designated location, which is separate from the decision-making process itself. The MDMP instead focuses on a structured approach to planning, namely the analysis of missions, developing and analyzing courses of action, decision-making, and production of orders.

In contrast, the other phases—Course of Action Development, Orders Production, and Mission Analysis—are integral components that ensure a comprehensive understanding of the mission requirements, generate viable plans, and effectively communicate those plans to ensure successful execution. Each of these parts helps to facilitate critical thinking, teamwork, and thorough preparation within the military framework.
