Special Forces Engineer Sergeant

The 18C is the Special Forces Engineer Sergeant — the demolitions, construction, and combat engineering specialist on a 12-person Operational Detachment Alpha (ODA). Inside the Green Beret community, the 18C is the team's go-to for breaching, target analysis, demolition calculations, vertical and horizontal construction, mountaineering tasks, urban combat engineering, and training partner-force engineers during Foreign Internal Defense (FID) missions. You came up through the same pipeline every Green Beret runs: Special Forces Assessment and Selection (SFAS), the Special Forces Qualification Course (SFQC), language training, and SERE — plus the 18C-specific engineer phase at the U.S. Army John F. Kennedy Special Warfare Center and School (USAJFKSWCS) at Fort Liberty.

That engineer phase is where 18Cs get the depth that sets the MOS apart from conventional combat engineers. You're trained on conventional and improvised demolitions, target analysis and shaped-charge calculations, urban breaching, field-expedient construction, mountaineering and high-angle work, light vehicle and small craft operations, and how to teach all of it to a host-nation engineer who may have never seen a det cord. Most 18Cs deploy with a Top Secret clearance, often with SCI access depending on the assignment, and accumulate years of operational tempo across the SOCOM theaters.

For employers, that combination is rare. You're not just an explosives guy and you're not just a builder — you're a credentialed combat engineer with active demolitions training, construction supervision experience, and the operational maturity that comes from running missions on a small team without a lot of supervision. Federal law enforcement bomb tech roles, defense contractor explosives and construction work, federal engineering positions, and commercial demolition and construction supervision all hire 18Cs out of uniform when the resume actually captures the engineering depth alongside the SOF tempo. Brad's career crosswalk tool lays out the civilian and federal paths side by side, and the 18B Weapons Sergeant and 18D Medical Sergeant pages cover sister roles on the team.

BMR has built more than 55,000 resumes across every MOS, and 18-series Green Berets carry one of the most distinctive backgrounds in the cleared workforce. 18Cs sit at a particularly strong corner. Credentialed demolitions, construction, and combat engineering plus an active TS clearance is a small pool. Federal LE bomb tech roles, defense contractor explosives work, and federal engineering positions hire 18Cs out of uniform when the resume captures the engineering depth alongside the operational tempo. — Brad Tachi, Navy Diver veteran & BMR founder

The civilian market for 18Cs splits into three clean lanes: explosives and bomb work, construction and demolition supervision, and federal law enforcement / defense contracting roles that want the cleared SOF engineer profile. Each lane pays differently and the geographic footprint is different.

Explosives and Bomb Tech Work

BLS tracks "Explosives Workers, Ordnance Handling Experts, and Blasters" under SOC 47-5031 — median wage $63,820 per BLS OEWS May 2024. That's commercial demolition, mining, quarrying, and construction-blast work. Higher-paying lanes sit in oil and gas (perforating, well-completion blasting) and large-scale demolition firms in major metros. Federal bomb tech roles pay materially more — see the federal section.

Construction Supervision and Project Management

Construction Manager (SOC 11-9021) median is $104,900 (BLS OEWS May 2024) and First-Line Supervisors of Construction Trades (SOC 47-1011) median is $77,670. 18Cs translate well into both because the SF engineer phase covers vertical/horizontal construction supervision, and FID missions train you to plan, sequence, and supervise builds with limited resources. The 12N Horizontal Construction Engineer page covers the conventional Army version of this lane.

Engineering Technician and Civil Tech Work

Civil Engineering Technologists and Technicians (SOC 17-3022) median is $60,700. This is the entry door for 18Cs who want to move toward project engineering or PE-track work without holding the degree yet. Many take this role while completing a B.S. on the GI Bill.

Defense Contractor and Cleared Roles

BLS doesn't track "defense contractor SOF engineer" as a separate occupation, but the cleared explosives / construction / training market is real and consistently pays above the BLS medians. Constellis, Amentum, V2X, KBR, and Booz Allen all run engineer and EOD-adjacent positions on government contracts that explicitly recruit 18-series and EOD veterans. The defense contractor jobs guide walks through how the clearance translates into compensation. For salary benchmarking on the broader military-to-civilian move, the military-to-civilian salary guide covers how to price your background.

Geographically, the strongest civilian markets for this background are the Gulf Coast, Texas, the Carolinas, the DC/Northern Virginia corridor, and the mountain west. Commercial demolition concentrates in major metros. Mining and oil-and-gas blasting sits in the Permian, Appalachia, and the Rockies. Federal contractor work clusters around DoD installations and the Beltway. Build your resume for the lane you actually want with the military resume builder.

Federal hiring is one of the strongest lanes for 18Cs because three things line up at once: the demolitions and explosives credential is rare in the civilian workforce, the active TS/SCI clearance fast-tracks federal background reinvestigation, and Veterans' Preference plus VRA/30% disabled appointment authorities give you real leverage on USAJobs. The trick is matching your experience to the right OPM series.

Federal Law Enforcement Bomb Tech (1811)

The GS-1811 Criminal Investigator series is where federal LE bomb tech roles live. FBI Special Agent (Bomb Technician), ATF Special Agent (Explosives Enforcement Officer), and U.S. Marshals Service positions all sit in 1811. Entry is typically GS-10/11 with a max entry age of 37 (Veterans' Preference can extend this). Promotion path runs to GS-13/14. Bomb tech specialty assignments require completion of the FBI Hazardous Devices School at Redstone Arsenal — your 18C demolitions background is directly relevant to passing that pipeline.

Engineering and Construction Series (0809, 0802, 0810)

The GS-0809 Construction Control Technician series matches 18Cs going into USACE, NAVFAC, or AFCEC quality assurance and construction inspection roles. GS-0802 Engineering Technician covers field engineering tech work supporting PEs. Both typically enter at GS-7/9 for veterans without a degree and GS-9/11 with one. USACE specifically recruits SF engineers for overseas construction supervision and FEST (Forward Engineer Support Team) positions.

Inspection, Investigation, Enforcement (1801)

The GS-1801 General Inspection, Investigation, Enforcement series covers federal explosives inspectors at ATF, mine safety inspectors at MSHA, and DOT hazmat enforcement. These are technical investigator roles, not 1811 special agent positions, and the entry age cap doesn't apply.

Police, Security, Safety (0083, 0080, 0019)

If federal LE bomb tech is the long game but you need a foothold while you study or wait on a 1811 hire, GS-0083 Police Officer at DoD installations or VA medical centers gets you into the system. GS-0080 Security Administration and GS-0019 Safety Technician also accept 18C backgrounds for explosives safety and antiterrorism roles. The 89D EOD Specialist page covers federal options that overlap heavily with 18C explosives work.

Miscellaneous Admin (0301)

The GS-0301 Misc Administration and Program series is the catch-all for SOF program managers, security cooperation positions, and SOCOM staff billets that USACE, DSCA, and SOF component commands hire into. 18Cs who liked the FID training side of the job often land here.

Build your federal package on the federal resume builder — federal resumes are written very differently from private sector ones (hours per week, supervisors, detailed duties) and BMR's tool handles the structure for you. When you're ready to apply, start your federal resume here.

If you're staying in explosives, demolition, federal LE bomb tech, or USACE-style engineering, your terminology translates directly. Recruiters in those lanes know what an ODA is, what a shaped charge is, what a target folder is, and what FID work looks like. Don't bury that vocabulary — it's what gets you the call.

This section is for 18Cs targeting careers outside the explosives and engineering specialty. Project management, operations management, corporate security, training and development, and supply chain leadership all hire SF engineers, but a hiring manager at a logistics company doesn't know what a "deliberate target" is. The translation is what costs callbacks. The 50 military terms translated to civilian language guide covers the broader vocabulary work.

Term Translation Examples

• Operational Detachment Alpha (ODA): 12-person cross-functional team operating with limited oversight.
• Target analysis / target folder: Site assessment and engineering feasibility study.
• Demolition calculation: Quantitative engineering analysis (forces, materials, structural reduction).
• Foreign Internal Defense (FID): International training and capacity-building program for partner organizations.
• Urban breaching: Controlled-entry methodology in built environments.
• Field-expedient construction: Resource-constrained construction project management.
• SFAUC (SF Advanced Urban Combat): Advanced tactical training certification.
• Robin Sage: Capstone unconventional warfare exercise (project leadership in complex environment).
