03 - INFANTRY

In addition to the Infantry Officer, Marine Gunner and Infantry Unit Leader, the 03 occupational field is comprised of the following specialties: Rifleman, Light Armor Vehicle Marine, Sniper, Reconnaissance Marine, Machine Gunner, Mortarman, and Antitank Missile Gunner.

 

Regardless of specialty, Infantry Marines are primarily employed in units from the team to regimental level to locate, close with and destroy the enemy in all environments and weather conditions, day and night.

 

Excluding LAR Units, Infantry Marines are principally trained to operate light and fast on foot. Infantry units are capable of multiple methods of entry and insertion, embarking aboard and fighting from helicopters, assault amphibious vehicles, motorized tactical vehicles, ultra-light tactical vehicles and small boats.

 

As a principal component of a Marine Air-Ground Task Force's Ground Combat Element, Infantry Marines must be able to operate effectively in austere, distributed environments characterized by friction, uncertainty, and chaos. In every operating environment, all Infantry Marines must be physically dominant and masters of small arms marksmanship, tactical combat casualty care, and battle drills.

 

Infantry units must be comprised of Marines proficient in the employment of demolitions, rockets, machine guns, mortars, missile systems, and capable of directing supporting arms.

 

As dictated by the operating environment, Infantry units must be comprised of Marines proficient in field craft and capable of employing unmanned systems, limited information warfare, and non-lethal systems.
