Administrative Specialist

The Marine Corps 0151 Administrative Clerk MOS is the legacy designation for what is now MOS 0111 Administrative Specialist. If you served as a 0151, you were doing the same core work that runs every S-1 shop in the Fleet: unit-level personnel admin, pay and entitlement transactions, awards processing, fitness reports, separations, and the official correspondence that makes the command operate. The work was done in MCTFS (Marine Corps Total Force System) and Marine Online (MOL), with paper Service Record Books and Officer Qualification Records maintained alongside the digital files.

Day-to-day, an 0151 ran reports, processed unit diary entries, audited pay, prepared travel orders, formatted naval correspondence per the SECNAV manual, and kept the command's awards and evals on the calendar. The volume was relentless, the deadlines were fixed, and "the document was wrong" was a sentence with consequences for the Marine whose pay or promotion depended on you. Camp Lejeune, Camp Pendleton, Cherry Point, Miramar, Okinawa, MCB Hawaii, Quantico, and HQMC at the Pentagon were the typical duty stations. The training pipeline ran through the Personnel Administration School at MCB Camp Johnson, NC.

That experience translates strongly to civilian HR, operations, records management, and federal admin. The HRIS data entry, records integrity, multi-system reconciliation, deadline pressure, and customer-facing work in a command climate are exactly what civilian operations and federal admin shops are buying.

If you are still working on the resume itself, this guide to converting fitness report and eval bullets into civilian resume bullets is the one to read first.

BMR has built more than 55,000 resumes across every MOS, and 0151s and 0111s tend to under-sell themselves harder than almost anyone in our data. "Admin specialist" reads as "paper-pusher" to civilian recruiters, but the reality is unit-level personnel, pay, awards, and reports management in a high-pressure command environment. That is exactly the package GS-0203, GS-0301, and corporate operations and HR managers are looking for. The translation is what wins the callback, and it is also where 0151 resumes often leave the most money on the table. — Brad Tachi, Navy Diver veteran & BMR founder

Civilian hiring managers do not see "0151" or "admin clerk." They see HR, operations, and records experience inside a heavy-volume, regulated, deadline-driven environment. The roles below are the most common direct paths for 0151s, with BLS OEWS (May 2024) median wages where the data is published.

Direct civilian roles

• Human Resources Specialist (BLS 13-1071, O*NET 13-1071.00) — full-cycle HR, employee relations, benefits administration, HRIS, onboarding. BLS median annual wage was $72,910 in May 2024.
• Compensation, Benefits, and Job Analysis Specialist (BLS 13-1141, O*NET 13-1141.00) — pay structure, benefits administration, classification. BLS median was $77,020 in May 2024 — a strong fit for 0151s who lived in MCTFS pay transactions.
• Executive Secretary / Executive Administrative Assistant (BLS 43-6011, O*NET 43-6011.00) — calendar, travel, correspondence, exec-level coordination. BLS median was $63,110 in May 2024.
• First-Line Supervisor of Office and Administrative Support Workers (BLS 43-1011, O*NET 43-1011.00) — office manager / admin team lead.
• Human Resources Assistant (BLS 43-4161, O*NET 43-4161.00) — HRIS data entry, records, onboarding paperwork.
• General Office Clerk / Records Manager (BLS 43-9061 / 43-4199) — files, correspondence, basic operations.

HR is currently steady-demand work, with hybrid and fully remote roles common at companies that have a real HRIS (Workday, ADP, UKG, SAP SuccessFactors). Picking up a recognized HR credential — aPHR, PHR, or SHRM-CP — accelerates placement, especially when you are coming in without a four-year degree. See the military-to-HR career guide for a full walkthrough.

If you are looking across the joint force, every branch has a personnel/admin specialty with the same translation: Army 42A Human Resources Specialist, Air Force 3F0X1 Personnel, Navy Yeoman (YN), Navy Personnel Specialist (PS), and Coast Guard YN. The civilian recruiter does not care which branch — they care whether you can run their HRIS and not break a payroll cycle.

Federal admin and HR is the highest-leverage path for many 0151s. The work is the closest analog to what you already did in the S-1, Veterans Preference is real, and the GS hiring system rewards the kind of structured, evidence-based resume that BMR is built to produce. Use the federal resume builder to generate the long-form, GS-formatted resume USAJobs requires.

The federal series 0151s most commonly land in

• GS-0203 Human Resources Assistance — entry path for personnel, in-processing, benefits, leave/pay, records. Common at GS-5/6/7. Direct match for 0151 SRB/OQR/MCTFS work.
• GS-0201 Human Resources Management — typically opens at GS-7/9/11, often with degree or specialized experience. The career path many 0151s grow into after a year or two as a 0203.
• GS-0301 Miscellaneous Administration and Program — broad admin/program support across DoD, VA, GSA. Strong fit when you describe the operational side of S-1 work, not just the clerical piece.
• GS-0303 Miscellaneous Clerk and Assistant — entry-level clerical / admin support, common at GS-4/5/6 inside DoD components.
• GS-0318 Secretary — executive support, often paired to a senior leader (SES, GO, agency director).
• GS-0335 Computer Clerk and Assistant — system data entry / records / HRIS-adjacent.
• GS-0341 Administrative Officer — installation, facility, or program admin lead. Pulls from S-1 OICs and senior 0151s/0111s often.
• GS-0343 Management and Program Analyst — process, reports, data analysis. The "what does the S-1 actually do at scale" series.
• GS-0344 Management and Program Clerical and Assistance — analyst-supporting clerical work.
• GS-0561 Budget Clerical and Technician — pay/budget transaction work for 0151s with strong MCTFS pay experience.
• GS-0560 Budget Analysis — typically degree-supported, available after time as a 0561 or with budget-relevant experience.
• GS-0308 Records and Information Management — for 0151s pivoting to a pure records discipline.

The strongest hiring pools for 0151s are VA (every regional office and medical center has 0203/0301 vacancies), DoD components (Navy, Marine Corps, and DoD agencies hire former Marines into civilian admin roles deliberately), GSA, OPM, and DLA. Apply Veterans Preference correctly on every application — the wrong DD-214 attachment is the most common reason a qualified veteran gets bypassed, not the resume itself.

If you are staying in HR, admin, or records, your terminology mostly translates as-is. Civilian HR recruiters know what unit diary, MCTFS, OQR, SRB, and FITREPs mean — or they will look it up in 30 seconds. This section is for 0151s targeting careers OUTSIDE HR/admin: project coordination, operations, compliance, customer experience, and data ops, where "Marine Corps Total Force System" reads as gibberish to a non-veteran hiring manager.

Term-by-term translation

• MCTFS / Marine Online → "Enterprise HRIS / personnel and pay system of record" (think Workday, ADP, UKG, SAP SuccessFactors)
• Unit diary → "Daily HRIS transaction log / personnel data integrity reporting"
• Service Record Book (SRB) / OQR → "Personnel file management / records lifecycle administration"
• Fitness Report (FITREP) administration → "Performance evaluation system administration"
• Awards processing → "Recognition program coordination and tracking"
• Naval correspondence (per SECNAV manual) → "Formal business correspondence / regulatory document preparation"
• Casualty reporting → "High-sensitivity case management with regulatory compliance"
• Pay and entitlement transactions → "Payroll/benefits transaction processing within an enterprise HRIS"
• Separations / discharge documentation → "Offboarding and exit documentation administration"
• S-1 shop / IPAC → "HR service center / shared services HR operations"

Resume bullets — before and after (non-HR target roles)
