The School Of Infantry (East)

Graduating from Marine Corps Recruit Training is a milestone few ever reach. After weeks of discipline, endurance, and transformation, new Marines finally earn the Eagle, Globe, and Anchor. But their journey doesn’t end at graduation. The next step is the School of Infantry (SOI), where Marines sharpen the combat fundamentals that define every Marine as a rifleman first.

What Is the School of Infantry?

The School of Infantry is where entry-level Marines transition from recruit to combat-ready warfighter. Every enlisted Marine reports to SOI:

Infantry Marines (03XX) train at the Infantry Training Battalion (ITB).

All non-infantry Marines attend Marine Combat Training (MCT).

Where Is SOI–East?

SOI–East is located at Camp Geiger, North Carolina, a satellite of Camp Lejeune on Marine Corps Air Station New River. Thousands of Marines pass through its gates each year to begin the next phase of their training.

Infantry Training Battalion (ITB)

For infantry Marines (03XX MOS)
Course length: Approximately 13 weeks

Training Includes:

Marksmanship and weapons proficiency

Patrolling and combat formations

Land navigation

Grenades and demolitions

Squad weapon systems

Tactical decision-making and field operations

Throughout ITB, Combat Instructors train, mentor, and evaluate Marines as they prepare for life in the Fleet Marine Force. After graduation, Marines report to their units ready for infantry service.

Marine Combat Training (MCT)

For all non-infantry Marines
Course length: Approximately 4 weeks

Training Includes:

Rifle marksmanship

Patrolling and maneuver

Basic combat tactics

Field skills and formations

MCT ensures that every Marine, regardless of MOS, remains a rifleman, prepared to fight if called upon.

Why SOI Matters

SOI pushes Marines to apply the discipline they built in boot camp to real-world combat skills. The pace is fast, the expectations are high, and the training builds confidence, in themselves, their abilities, and their fellow Marines.

For Families & Supporters

Your Marine may be out of boot camp, but they are still in a demanding training environment. Field time, long training days, and limited liberty mean phone access is inconsistent. Once again, letters often become the most reliable way to stay connected.

Every message from home is a reminder that their effort and commitment are seen and supported.

Communication at SOI–East

Because much of the training happens in the field, Marines may go days without using their phones. Families can continue sending letters and updates through Sandboxx, and the SOI–East mailing address is available here.

If your Marine wears glasses, they are required to report to SOI-E with their USMC issued prescription glasses. This is a non-negotiable requirement, and Marines that forget their glasses could be held from training for several weeks.
