The Engineer, Construction, Facilities, and Equipment occupational field comprises Marines whose duties include metalworking and welding; repair, maintenance, and operation of engineer heavy equipment such as cranes and bulldozers; construction and repair of military structures and facilities; clearing and emplacing obstacles such as minefields; construction of standard and nonstandard bridging; and emplacing and detonating explosives for construction and demolition projects. Also, some Marines in the field work with the storage and distribution of bulk fuel products. The opportunity to participate in a formal apprenticeship program leading to receipt of a Department of Labor Certificate of Apprenticeship Completion may be available in some MOSs within occupational field 13. There are a variety of challenging and interesting billets available in occupational field 13, ranging from inspector-instructor duty, to duty with operating forces (MARDIV, MLG, or MAW) or the supporting establishment.

Are there any prerequisites to becoming a Combat Engineer Officer

Officers must meet the Ground Combat Arms MOS Classifications Standards. For the Physical Fitness Test, officers must perform at least 6 pull-ups and run 3-miles in 24:51 or less. For the Combat Fitness Test, officers must perform at least 60 ammo can lifts, run the movement to contact in 3:26 or less, and navigate the maneuver under fire in 3:12 or less.

Where do I go after TBS?

After TBS, officers will go to the 112 day Combat Engineer Officer Course (CEOC) at the Marine Corps Engineer School (MCES) aboard Courthouse Bay, MCB Camp Lejeune, NC. The purpose of the course is to provide entry-level training to the Combat Engineer Officer for duty in the Operating Forces. The course includes instruction in basic and supervisory level operational and planning skills in engineering related subjects pertaining to staff administration, mobility, countermobility, survivability, demolitions, reconnaissance, maintenance and general engineering.

What is it like being a Combat Engineer Officer?

A typical first tour assignment for a Combat Engineer is within a Combat Engineer Battalion (CEB) as part of the GCE, Engineer Support Battalion (ESB) as part of the LCE, or Marine Wing Support Squadron (MWSS) as part of the ACE of the MAGTF. There are CEBs subordinate to 1st and 2nd MARDIV as well to 4th MARDIV as part of MARFORRES: 1st CEB aboard MCB Camp Pendleton, CA (1st MARDIV); 2nd CEB aboard MCB Camp Lejeune, NC (2nd MARDIV); and 4th CEB in Baltimore, MD (4th MARDIV). Combat Engineers assigned to a CEB in their first tour may serve as a Platoon Commander in direct support of an infantry battalion or battalion landing team (BLT) and are responsible for training and employing their platoon and engineer equipment in support of the battalion’s scheme of maneuver.

There are ESBs subordinate to each MEF as well as the reserve MLG: 7th ESB aboard MCB Camp Pendleton, CA (1st MLG); 8th ESB aboard MCB Camp Lejeune, NC (2nd MLG); 9th ESB aboard MCB Camp Hansen, Okinawa, Japan (3rd MLG); and 6th ESB in Portland, OR (4th MLG). Combat Engineers assigned to an ESB in their first tour may serve as a Platoon Commander within the Engineer Support Company, Combat Engineer Company, or Bridge Company and are responsible for training and employing their platoon to be able to provide combat engineering and limited general engineering, bulk liquid, and utility support to the MAGTF. There are MWSSs subordinate to each active duty and reserve MAW. See Appendix C, D, E, and F for the location of each MWSS. Combat Engineers assigned to an MWSS in their first tour may serve as a Platoon Commander of the Heavy Equipment Platoon, Utilities Platoon, or Combat Engineer Platoon within the Engineer Operations Division and are responsible for training and employing their platoons to provide limited combat and general engineering support to designated components of the ACE.
