M2, fires, sustainment, protection and ____

• A. Commanders intent
• B. Visualize
• C. Command and control
• D. Understand

Answer: (C)

The main idea is how the Army organizes and synchronizes its operations. Maneuver, Fires, Sustainment, and Protection are the four warfighting functions, and the missing element is Mission Command, which is the doctrine term for command and control. Mission Command provides the framework for authority, decision-making, and information flow so leaders can set a clear intent and empower subordinates to act with initiative. This shared understanding and decentralized execution lets fires, movement, sustainment, and protection be coordinated effectively across the battlefield. That’s why the best completion is the concept commonly referred to as command and control.
