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.
