Marine Corp Infantry MOS: A Glimpse into Life as a Marine Infantryman

The United States Marine Corps offers a wide range of Military Occupational Specialties (MOS) for enlisted Marines to serve their country. One of the most iconic and respected MOS is the Marine Infantryman, also known as 0311. As an infantry rifleman, you'll be part of the frontline forces, tasked with locating, closing with, and destroying the enemy by fire and maneuver or repelling their assault through close combat.

The training period for this MOS is a grueling 59 days at the United States Marine Corps School of Infantry, located at Camp Geiger in North Carolina or Camp Pendleton in California. Once assigned to your unit, you'll be part of a rifle squad, where noncommissioned officers serve as fire team leaders, scout team leaders, rifle squad leaders, or rifle platoon guides.

As a rifleman, your primary role is to act as the primary scouts, assault troops, and close combat forces available to the Marine Air Ground Task Force. You'll be equipped with a range of weapons, including the M4 carbine, M203 grenade launcher, M27 Infantry Automatic Rifle, AT4 and M72 LAW rockets.

Life as a Marine infantryman is never easy, and the training period is just the beginning. In my experience, every day presents new challenges, from intense combat situations to grueling physical training. As an infantryman, you'll be expected to adapt quickly to changing circumstances and work seamlessly with your teammates to achieve your mission objectives.

Despite the difficulties, being part of the Marine Corps Infantry offers a sense of camaraderie and purpose that's hard to find elsewhere. Whether serving in Iraq or Afghanistan, as a Marine infantryman, you'll have the opportunity to make a real difference on the battlefield and be proud of your service.

In this article, we've provided an overview of the Marine Infantry MOS, highlighting its core responsibilities and the challenges that come with being part of the frontline forces. If you're considering a career in the United States Marine Corps as an infantry rifleman, remember that it's not just about the job – it's about serving your country and being part of a proud tradition of service and sacrifice.
