Learn About Being a Rifleman in the Marine Corps
Enlisted Job Descriptions - MOS 0311
"Every Marine is a Rifleman" has been the mantra of the United States Marine Corps since there have been Marines fighting wars. Though it does not mean that every Marine has the MOS 0311 of the actual infantry rifleman, it does mean that every Marine - from food specialists to logistics personnel - have been trained in the basics of being a rifleman. The Marine Corps built the entire service around the training and support of the Infantry Rifleman.
All non-infantry personnel (POGS - People Other than Grunts - a term 'affectionately' used by the Infantry) will attend basic infantry skills at the USMC School of Infantry (SOI) in a separate infantry training program called the Marine Combat Training (MCT). Being able to pick up a weapon and defend yourself and your fellow Marines when needed is more what the phrase "Every Marine is a Rifleman" means.
The Infantry MOSs attend the actual SOI Infantry Training Battalion (ITB). This is where the MOS0311 Rifleman learns the skills to operate within an Infantry Unit. This Infantry MOS is earned through the ITB school and will be the primary military occupational specialty (PMOS) of the Marine finishing ITB.
Rank Range: Sgt to Pvt

The riflemen are the foundation of the Marine infantry organization, and as such is the nucleus of the fire team in the rifle squad, the scout team in the LAR squad, scout snipers in the infantry battalion, and reconnaissance or assault team in the reconnaissance units.
