You spent years as an MP, a master-at-arms, or a CID agent. You ran investigations. You enforced standards. Now you want a federal job that uses that work. The GS-1801 series keeps showing up in your USAJOBS searches. But the announcement reads like a wall of code words.

I get it. When I left the Navy, I sent federal applications for a year and a half with zero callbacks. The problem was not my experience. It was how I described it. I had no idea how to map what I did in uniform to the words a federal panel scores. Once I cracked that, the doors opened. This guide does that mapping for the 1801 series.

By the end you will know what the 1801 series is, how it differs from the criminal investigator series, which military jobs fit it, and how to write a resume that gets you referred.

What Is the GS-1801 Federal Job Series?

GS-1801 is the General Inspection, Investigation, Enforcement, and Compliance Series. It sits inside the 1800 occupational group at OPM. Think of it as the catch-all series in that group.

The federal government uses 1801 in two cases. First, when a job mixes work from two or more 1800 occupations and no single one is the main duty. Second, when the work fits the group but no other established series covers it. So 1801 is broad by design.

The 1800 group covers inspection, investigation, enforcement, and compliance work across many agencies. Customs. Immigration. Aviation safety. Consumer product safety. Mine safety. Environmental compliance. The 1801 series is where the mixed or unique roles land.

One quirk to know. OPM does not set a fixed title for the 1801 series. Agencies build their own titles. So you might see "Compliance Officer," "Program Inspector," or "Enforcement Specialist," all coded 1801. Read the duties, not just the title.

How Is GS-1801 Different From GS-1811 Criminal Investigator?

This trips up a lot of veterans. The two series sound alike. They are not the same.

GS-1811 is the Criminal Investigator series. These are federal special agents. FBI, HSI, ATF, DEA, Secret Service, and agency Offices of Inspector General hire 1811s. The work centers on criminal cases, arrests, and federal court. The 1811 series also carries special law enforcement retirement under 6(c). That means earlier retirement and a higher pension rate.

GS-1801 is broader and usually not a gun-and-badge criminal role. It covers inspection, compliance, and administrative investigation work. Most 1801 jobs do not carry 6(c) retirement. Some do carry enforcement authority, but the focus is rules and standards, not criminal prosecution.

Why does this matter for your resume? Because if you target 1801 with a resume built for an 1811 arrest role, the keywords miss. And if you want 1811 but only qualify for 1801 right now, the 1801 job can be your foot in the door.

Which Military Backgrounds Fit the 1801 Series?

A lot of them. The 1800 group rewards people who enforced rules and ran investigations. The military builds that skill in many jobs.

Here are common fits:

• Army Military Police (31B) and CID agents: patrol, investigations, evidence, and law enforcement reports map well.
• Navy Master-at-Arms (MA) and NCIS support roles: security enforcement, investigations, and access control fit.
• Air Force Security Forces (3P0X1) and OSI support: enforcement, inspections, and incident reports translate.
• Marine MPs and CID Marines: same enforcement and investigation base.
• Inspectors and compliance roles: safety, supply, and standards inspectors across all branches.

You do not need a criminal justice degree for most 1801 jobs. The series qualifies on experience. That is good news for enlisted veterans who learned the work on the job.

If your background is straight law enforcement, you may also want to read our guide on moving from military police to civilian law enforcement. It pairs well with a federal 1801 search.

How Do You Qualify for GS-1801?

OPM uses the Group Coverage Qualification Standard for Administrative and Management Positions for the 1801 series. Some agencies add Individual Occupational Requirements on top. You can read the official standard on the OPM 1801 qualification page.

Qualification comes down to specialized experience. That means experience that prepared you to do the job. It must be at a level close to the next grade down. Here is the rough ladder:

The key word is specialized. Your resume must show experience that matches the duties in the announcement. General service is not enough at higher grades. You need to prove you did the inspection, investigation, or compliance work itself.

How Do You Write a Federal Resume for the 1801 Series?

This is where most veterans lose the job before a human ever reads the file. The announcement lists duties and key skills. Your resume must mirror that language. USA Staffing scans for it. A weak match sinks to the bottom of the pile.

Federal resumes run two pages now. OPM changed the old long-form standard in November 2025. So make every line count. Use plain words. Show the work, then show the result.

Notice the fix. The strong bullet names the work in 1801 terms. It uses numbers. It shows a result. That is what a federal panel scores.

Match these resume keywords to the 1800 group when they fit your real work:

• Investigation: case management, evidence handling, interviews, report writing.
• Compliance: standards review, audits, corrective action, policy enforcement.
• Inspection: site visits, findings, documentation, follow-up.
• Enforcement: violations, citations, regulatory authority, due process.

Pull your real numbers from your service records and evaluations. Use your NCOERs, FITREPs, or award write-ups. They hold the metrics a federal resume needs. Do not pull from your DD-214. It only lists service dates and discharge status.

If the federal-to-civilian translation feels like a foreign language, that is normal. BMR's Federal Resume Builder handles the keyword matching and the two-page format for you. Paste the announcement, and it tailors your resume to that specific 1801 job. Built by veterans who have run the federal hiring gauntlet.

Before you apply, check your veteran hiring path. Many veterans can use the Veterans Recruitment Appointment to get hired up to GS-11 without full open competition. And know the federal hiring timeline so the wait does not catch you off guard.

What Mistakes Cost Veterans the 1801 Job?

I have seen the same errors over and over. Each one is easy to fix once you know it.

The first mistake is copying your old TAP resume. That resume was built for a generic job. The 1801 announcement is specific. A generic resume ranks low and never reaches a human.

The second mistake is heavy military jargon. A federal reviewer may not know your unit codes or acronyms. Spell the work out in plain words. Say "investigations" not a slang term. Say "compliance review" not an internal program name.

The third mistake is leaving out numbers. A line with no metric reads weak. How many cases? How fast? What result? Numbers turn a duty into proof.

The fourth mistake is applying late. Many federal jobs close when they hit a set number of applicants. Some close in days. A saved search and a ready resume keep you early in the stack.

Fix these four things and you move ahead of most of the field. Most applicants never do.

Which Agencies Hire for the GS-1801 Series?

The 1800 group spans the federal government. So 1801 jobs show up in many agencies. The work changes by mission, but the core skills stay the same.

Here are common employers to watch on USAJOBS:

• Department of Homeland Security: Customs and Border Protection, TSA, and other components hire inspection and compliance staff.
• Department of Labor: OSHA, the Mine Safety and Health Administration, and Wage and Hour run inspection and enforcement work.
• Department of Transportation: aviation, rail, and motor carrier safety programs need inspectors.
• Environmental Protection Agency: compliance and enforcement roles check that sites meet federal rules.
• Department of the Interior: resource protection and program compliance roles use the 1801 series.
• Offices of Inspector General: nearly every agency has one, and many run program investigations.

Set up a saved search on USAJOBS for series 1801. Add your locality and grade range. New jobs hit the board every week. The early applicant has the edge, so check often.

What Does Specialized Experience Look Like for 1801?

Specialized experience is the heart of your application. The panel reads it first. It must match the duties in the announcement. Vague service language fails here.

Say the job asks for experience conducting investigations and writing findings. Your resume should show that exact work. Name the case types. Give the volume. Show the outcome. A line like "conducted 60 security investigations and wrote findings used in command action" beats "performed law enforcement duties."

Say the job asks for compliance review experience. Show where you checked work against a standard. Show what you did when you found a gap. A line like "audited 200 supply records monthly and corrected 30 discrepancies" proves the skill.

Match the grade too. For a GS-9 job, your experience must read at the GS-7 level of difficulty. That means independent work, not just helping someone else. Show that you owned the task. Show that you made the call.

One more tip. Mirror the announcement's key phrases in your own words. If it says "regulatory compliance," and you did that work, use that phrase. The match helps you rank in USA Staffing. It also helps the human reviewer connect the dots fast. For the deeper qualification rules, our GS-1101 series guide walks the same group-standard logic for a sister series.

Is the GS-1801 Series Worth Targeting?

Yes, for many veterans it is one of the best entry points into federal service. The series is broad. The agencies are many. And the work lines up with what you already did in uniform.

Start by reading the duties in each announcement. Match your resume to those exact words. Pull real numbers from your service records. Use your veteran hiring path. Then apply with a clean two-page federal resume.
