USMC Responsibilities
1371 Combat Engineer is described here by practical Marine Corps duties, billet expectations, and training progression. This section avoids game-language so the page reads like a professional MOS reference.
- Support mobility, countermobility, survivability, construction, demolitions, breaching, and engineer equipment operations.
- Coordinate engineer support to maneuver units, base camps, route work, obstacle reduction, and field fortifications.
- Maintain technical equipment, safety procedures, explosives accountability, and engineer planning products.
- Train teams to operate in field conditions with disciplined risk management and accurate reporting.
Training Pipeline
The pathway is shown at a broad public level. Exact prerequisites, screening, quotas, course names, and assignments can change by fiscal year, manpower requirement, medical qualification, command screening, and schoolhouse policy.
- Complete entry-level Marine training and engineer MOS school.
- Qualify on engineer tools, equipment, demolitions, obstacle work, construction, survivability, and safety procedures required by the MOS.
- Serve in engineer battalions, combat logistics elements, or attached support billets.
- Advance into team chief, section leader, equipment chief, engineer officer/warrant officer, or staff planning roles.
Billets And Skill Growth
- Entry-level Marines focus on core tasks, equipment, field discipline, and reliable execution.
- NCOs supervise small teams, enforce standards, plan rehearsals, and train junior Marines.
- SNCOs and officers manage readiness, risk, training plans, inspections, reporting, and integration with adjacent staff sections.
- Instructor and staff billets preserve standards, document lessons learned, and build repeatable training for the next rotation.
Chain of Command Matching Logic
Chain of command records can list a current MOS, prior record MOS, ADMOS, or specialty track. This page shows a member as a Current MOS when the MOS is the member’s active specialty and as Recorded Profile MOS / ADMOS when it appears in the member history.
Rank / Grade Requirements
Grade LaneEnlisted MOS
Entry / Award Basis
Combat Engineer MOS after recruit training, Marine Combat Training, and combat engineer MOS school.
Typical Rank Use
Pvt through Sgt for engineer team and squad billets; SSgt through MGySgt for platoon, company, operations, and engineer chief billets.
Schoolhouse & Qualification Requirements
SchoolhouseMarine Corps engineer schoolhouse / engineer equipment and combat engineer training pipeline
Engineer training covers mobility, countermobility, survivability, demolitions, obstacle reduction, equipment employment, and construction support as specialty requires.
Entry QualificationsScreening / Prerequisites
Requires engineer-field classification, medical qualification, safety screening for demolitions/equipment, licensing where required, and course completion.
Associated SchoolsFollow-On Training
- Demolitions and breaching sustainment
- Engineer equipment licensing / supervisor training
- Route clearance and obstacle reduction training
- Leader and instructor schools by billet
Course titles, quotas, prerequisites, and sequence can change by fiscal year, manpower requirement, medical qualification, and current schoolhouse policy.
