What is the primary mission of an infantry regiment?

• A. To locate, close with and destroy the enemy by fire and maneuver
• B. To conduct maritime interdiction operations
• C. To provide close air support
• D. To perform logistics supply

Answer: (A)

The main idea here is the core role of ground infantry in combat: fighting on the move by fire and maneuver to defeat the enemy. The phrase “locate, close with and destroy the enemy by fire and maneuver” sums up how infantry regiments engage—finding the foe, closing the distance, and delivering coordinated fire while maneuvering to gain and hold advantageous positions, ultimately destroying or significantly defeating the enemy. This combination of contact, movement, and decisive engagement is what infantry units do best on the ground in a contest for terrain and leadership of the fight.

Other military tasks belong to different domains or support functions. Maritime interdiction operations are conducted by naval forces at sea, close air support is provided by air assets, and logistics supply is about sustaining troops with needed materiel. While an infantry regiment works with or is supported by these elements, its primary mission remains ground combat through locating, closing with, and destroying the enemy by fire and maneuver.
