What is the mission of the U.S. Army?

• A. To defend the United States from external threats.
• B. To fight and win wars by providing sustained land dominance.
• C. To maintain naval superiority on the oceans.
• D. To achieve air superiority.

Answer: (B)

The Army’s mission centers on land warfare: to fight and win the nation’s wars by delivering sustained land dominance. That means being able to project power on the ground, seize and hold terrain, and keep forces operating effectively over time through strong logistics, maneuver, firepower, and resilience. This focus on ground combat and prolonged operations uniquely defines the Army, while other services handle different domains—naval superiority is the Navy’s responsibility, and air superiority is the Air Force’s. National defense against external threats is a broad task that involves all branches, with the Army contributing its capabilities on land.
