Infantry Officers are central to the role of the Marine Corps as an expeditionary force. They are responsible for training their Marines for every variety of ground combat mission in any environment. They gather and evaluate intelligence on enemy forces, develop offensive and defensive battle plans and command their infantry unit's use of weapons and equipment.

Within the MAGTF
Infantry officers are members of the Ground Combat Element within the Marine Air-Ground Task Force (MAGTF) and participate in the discipline, morale, and welfare of their unit's Marines as well as planning, directing and assisting subordinate infantry and reconnaissance units.
Beyond Your First Tour
After your first tour, you may be assigned to a billet available to all officers, such as recruiting duty, instructor duty at The Basic School or series commander at one of the Marine Corps Recruit Depots. Later in your career, you may be assigned to Expeditionary Warfare School or seek an advanced degree. This pattern of assignment is designed to expand your knowledge of the Marine Corps and overall strategic operations before you take on increased responsibility within your MOS.
MAGTF refers to the unique four-part structure that organizes Marine Corps operating forces. This framework brings together Aviation, Ground and Logistics Combat elements under a central Command element. The result is a flexible, combined-arms unit with the capabilities to conduct the Marine Corps' full range of operations, from humanitarian aid and disaster relief to projection of power from the sea.
MAKEUP OF A MEU
A MEU, or Marine Expeditionary Unit, is the smallest type of MAGTF, often providing the most substantial response in the shortest amount of time. 2,200 Marines that are trained in hundreds of areas of expertise serve on a MEU. Here is the breakdown of a MEU's makeup:
Command Element – Approximately 200 Marines. Responsible for command and control of the entire MEU.
Ground Combat Element – Approximately 1,200 Marines. A Battalion Landing Team that includes three rifle companies, a weapons company, a battery of artillery and platoons of the following: combat engineers, light armored reconnaissance, tanks, Force Reconnaissance and amphibious assault vehicles.
Aviation Combat Element – Approximately 500 Marines. A MEU's ACE is built around a medium tilt-rotor squadron, reinforced by CH-53E heavy lift helicopters, light attack helicopters and Harrier attack jets. The result is a squadron of 25 to 30 aircraft.
Logistics Combat Element – Approximately 300 Marines. Provides supply, transportation, maintenance and additional support for the MEU.
