What is the mission of the Army?

• A. To defend the homeland with naval and air power.
• B. To deploy, fight, and win our Nation's wars by providing ready, prompt, and sustained land forces.
• C. To manage intelligence and cyber operations.
• D. To provide disaster relief only.

Answer: (B)

The mission being tested is the Army’s defining purpose: to project decisive land power in defense of the nation. This means deploying, fighting, and winning our Nation’s wars by providing ready, prompt, and sustained land forces. In practice, that capstone idea links up several core ideas: the Army specializes in ground combat power—soldiers, armor, artillery, engineers, and logistics—that can be rapidly moved to a problem area, fought on land, and kept operating over time to achieve strategic objectives.

Consider what “land forces” imply: the capacity to maneuver on and control territory, coordinate with air and joint assets, and sustain operations through logistics, medical care, maintenance, and supply. The emphasis on readiness and prompt deployment highlights the need to be prepared to respond quickly to threats or crises. The “sustained” aspect underlines the ability to fight over extended periods and support allies as needed.

Why the other options don’t fit as the Army’s mission: naval and air power are the domains of the Navy and Air Force, not the Army. The Army participates in joint operations, but governing intelligence and cyber operations is the purview of specialized commands and other services that focus on information and cyberspace domains. Disaster relief, while something the Army can assist with, is not the Army’s primary purpose or its central mission.
