The MOS 0351 - USMC Infantry Assaultmen are found in the assault sections of weapons platoons of the infantry rifle companies. The training path of the Infantry Assaultman is similar to all Marines until School of Infantry (SOI) and depending upon where you attend recruit training will determine with SOI you will attend:

The Marine Corps Infantry has two training schools where Marines will attend after recruit training depending upon which coast of the United States they are located in:

The East Coast Infantry Training School is located at Camp Geiger (a satellite facility of Camp Lejeune) in Jacksonville, North Carolina. This is the School of Infantry (SOI) in the Eastern Region. Camp Geiger is the next step for the Enlisted Marines trained at Parris Island. Marines who complete Recruit Training at MCRD San Diego move on to SOI West, located at Camp Pendleton, in Southern California.

Following recruit training and graduation, new Marines report the School of Infantry (SOI).

  • Training at SOI ensures every Marine has the capability to fulfill his or her duties while operating in a combat environment.
  • SOI mantra: "Every Marine a rifleman."
  • SOI is made up of two schools: Infantry Training Battalion (ITB) and Marine Combat Training (MCT).
  • Infantry Military Occupation Specialty (MOS) Marines are assigned to ITB, which instills all basic Infantry skills and some advanced infantry skills, for Marines who are going out to the fleet.
  • Non-infantry MOS Marines are assigned to MCT to hone all basic infantry skills.
