Which of the following is NOT one of the seven Army warfighting functions?

• A. Intelligence
• B. Sustainment
• C. Logistics
• D. Fires

Answer: (C)

The idea being tested is how the Army groups activities into warfighting functions and what name is used for the logistics-related work. In Army doctrine, sustainment is one of the seven warfighting functions, and it covers the planning, coordination, and execution of logistics-related tasks like supplying, maintaining, transporting, and supporting units. Logistics, while essential, is not named as a separate warfighting function; it is the set of activities that fall under sustainment. That’s why logistics isn’t listed as one of the seven functions, making it the correct choice for “not one of the seven.” The other options—intelligence and fires—are explicit warfighting functions, and sustainment is itself a warfighting function, with logistics functions included inside it.
