Which unit type is primarily trained to engage in direct ground combat and seize terrain?

• A. Combat Support
• B. Non-Combat Arms
• C. Infantry (Combat Arms)
• D. Special Operations

Answer: (C)

Infantry are the Marines’ ground combat specialists, trained to engage directly with the enemy on the ground and seize terrain. Their core mission is to move, assault, and hold objectives, which means they practice close-quarters tactics, maneuver warfare, and overpowering enemy positions to capture key ground features. The other options provide support or specialized roles that enable combat operations but are not primarily tasked with the direct ground assault to seize terrain. Combat Support, Non-Combat Arms, and Special Operations each have different primary focuses, whereas Infantry (Combat Arms) is defined by the direct ground assault and terrain seizure role.
