How to write a cover letter after the military

A civilian reader may not know what an NCOIC, a flight or a billet is. Your cover letter has to say what you did in words they know, and why it fits their job.

If you're getting out this year, almost everything you've written in uniform was for a reader who already knew the vocabulary. Evaluations, award citations and memos take it for granted that the reader knows what an NCOIC, a flight or a billet is. A civilian hiring manager may not. A cover letter is one place in an application where you can talk to that person directly.

In this guide, "cover letter" means the letter you send with a job application. It isn't the "Cover Letter" option on milConnect's VMET tab, a PDF that, in milConnect's words, "provides general information about the VMET document."

The Labor Department's (DOL's) Employment Workshop guide prints two sample letters: a business consultant's on page 61 and, in its appendices on page 194, one from a 12-year military veteran applying to be a facility security officer. CareerOneStop's sample letter is also a business consultant's, and its veterans page on cover letters has no sentence about military service. Neither shows a letter paragraph in military shorthand and then rewritten in plain words, so the example here is our own: a fictional Air Force technical sergeant, built from the rules those sources give. It isn't an official model. Here is one paragraph of her draft, written two ways.

Do you need one?

Start with the posting. CareerOneStop, a career site sponsored by the Labor Department, sorts the question into three cases. If the posting asks for a cover letter, write one. If the employer asks you to email your résumé, the body of the email can be the letter.

If the letter is optional, CareerOneStop says it's a good idea to include one. Its reasons are to show how you match the job, explain employment gaps or issues, or describe your special interest in the job and employer. Under its "When should I include a cover letter?" heading, the page says many employers don't ask for one and your résumé can often tell them everything they need.

Leaving the service isn't one of CareerOneStop's listed reasons, but two of them fit. If the last title on your record is a military one, such as NCOIC of a supply element, a short letter can say what the work was in words the reader knows. If you're moving into a different line of work, it can say why you want this job.

The four paragraphs

DOL's participant guide, written for separating service members, says a typical cover letter runs 250 to 400 words in a set format. CareerOneStop says about 200 to 400 words in 3 to 4 short paragraphs, and its Veterans page says a letter should normally fit on one page. Aim for 250 to 400 words, which sits inside both ranges. The format boils down to four paragraphs.

Two rules cut across all four. The letter shouldn't repeat your résumé: DOL says so, and CareerOneStop says to use different examples or language than your résumé does. And paragraph three is one story, not a list of duties. DOL's advice is to pick a story from your career that gives the reader a clear idea of who you are and how you can add value.

Address the letter to a person if the posting names one. DOL's template says not to write "To whom it may concern" and to use Ms. rather than Mrs. or Miss. With no name, DOL allows "Hiring Committee," and CareerOneStop suggests the recipient's job title or "Search Committee." DOL's own veteran sample is addressed to a named person and signs off "Best Regards."

For the close, DOL's template gives "Sincerely" or "Best Regards" and says not to use V/R. DOL calls "I'll call to schedule an interview" too aggressive coming from an applicant, but CareerOneStop's own sample letter ends "I'll call you next week," so the two sources differ. "I look forward to hearing from you" matches what both allow.

Say it in words a civilian reader knows

CareerOneStop's rule is the one that matters most here: substitute civilian equivalents for military terms, titles, ranks and acronyms as you write your cover letters and résumés. On titles, it says not to get caught up in Captain, Major or Sergeant, and to communicate the functional area of the job.

In practice that means three swaps. A title becomes what the job was. A unit's name becomes what the unit did. An acronym becomes plain words, or it comes out. CareerOneStop's own tables of possible civilian terms give squad leader as team leader or team chief, NCOIC as supervisor, manager or coordinator, and TDY as business travel. It works at any rank. A fictional infantry corporal (E-4) who led three other soldiers writes "I led a four-person team" and leaves out the rank and the unit's name.

The first figure shows a fictional paragraph both ways. Notice what doesn't change, which is the value of every figure. Your numbers have to be true, and they have to come from your own record, such as an evaluation, an award citation or your orders. DOL says to use specific numbers where you can, and to be honest: a skill you state or imply and don't have will come back to haunt you. Translating isn't upgrading. A team of 14 stays a team of 14, and any civilian title you borrow, from CareerOneStop's translation tables or anywhere else, should match what you actually did.

Evaluations to résumé bullets shows how to pull numbers out of your records, tailoring without lying covers using a posting's words for work you really did, and the military-to-civilian résumé guide covers the résumé your letter sits next to.

What to leave out about your service

Some limits are firm. Classified information doesn't belong in a letter. Under Executive Order 13526, access to it requires a favorable eligibility determination, a signed nondisclosure agreement and a need to know. If you signed an SF 312, the ODNI's FAQ for the form says a previously signed nondisclosure agreement "remains in full force and effect for the lifetime of the individual," so it doesn't end when you separate. Classified information isn't limited to documents with a marking. The same pamphlet defines it as "any marked or unmarked information" that law or executive order requires to be protected, and says unauthorized disclosure is illegal and may bring administrative, civil or criminal penalties.

If you held a clearance, DOL's veteran sample letter shows one way to say so: "I currently hold a Secret security clearance." The line gives a level and nothing about the work done under it. Whether you can still say "currently hold" once you've separated is a separate question, and the security clearance guide covers it.

Unclassified doesn't always mean shareable. The National Archives describes controlled unclassified information as information that requires safeguarding or dissemination controls under law or policy even though it isn't classified.

Past that, the sources get thinner. DoD's OPSEC awareness course is about protecting unclassified information on operations and personal information, and it's for current members, DoD employees and contractors. Military OneSource's checklist for service members and families lists where service members are stationed, specific dates and locations, and their jobs among the things not to post during a deployment. Neither says whether it reaches a veteran's letter to an employer.

For public release, DoD says retired and separated members use its prepublication review process. It doesn't say whether a letter to one employer counts. So describe the work by its function and results, as CareerOneStop and DOL ask, with team sizes and dollar figures only where they're true. If you aren't sure a detail can be said, leave it out.

If you're still in uniform

A letter sent before your separation date is a contact with a future employer, and it can fall under DoD's ethics rules on seeking employment. The Standards of Conduct Office handout on the subject, which carries the Department of War name, lists "making an unsolicited communication to a prospective employer" about future employment as seeking employment. It says requesting a job application is not.

Air Force ethics guidance says government email may be used for a job search during personal time with your supervisor's permission. It adds that you shouldn't assume that use is authorized unless you clear it in advance. We read only the Air Force's version of that rule, so ask your command ethics official about your branch's, and about how the rules apply to a given employer. The networking messages and recruiter phone screen guides cover those rules in more detail.

Federal jobs

On a federal application, the announcement decides. DOL's guide says the Required Documents section lists the documents you may need to include to confirm you're eligible and qualified, and its examples start with a cover letter. Missing documentation may leave an application "incomplete and not considered."

In DOL's list, the letter sits with two veteran documents, the SF-15 for 10-point preference and the DD-214, both marked "if appropriate." If you apply before your DD-214 is issued, DOL says to ask the job posting's point of contact about alternates such as a Statement of Service. The veterans' preference guide covers the SF-15.

The four short essay questions are a separate thing. OPM's Merit Hiring Plan FAQ, issued in 2025, says the answers aren't scored and that agencies should treat them the way they would treat a cover letter. OPM has changed the essay rules since, and the federal résumé guide has the current ones.

What the hiring software does with it

DOL's guide describes an applicant tracking system, or ATS, as software that compiles résumés and uses the employer's requirements and keywords to find the most qualified candidates. It says nothing about cover letters in that section. Its keyword tip is for the résumé: use both the long-form and acronym versions of a keyword, as in "Master of Business Administration (MBA)." For a service record full of acronyms, that means the plain words with the acronym beside them on the résumé, while the letter follows CareerOneStop's rule of civilian terms. To see how each system treats a letter, we read the documentation from six hiring-software vendors.

In these documents, a letter is a stored file or a text box. The matching and parsing pages we read describe the résumé: Greenhouse's matching draws on submitted résumés, and Greenhouse's and Workday's parsers fill in fields from the résumé. Workday's recruiting privacy statement, effective June 3, 2026, covers Workday's own hiring and says an AI tool extracts skills, experience, location and education "from within candidate applications and resumes/CVs." It lists "application letters" among the information Workday processes and doesn't name them in the AI passage.

You'll see sites claim that these systems scan a letter for keywords. None of the six documents says that, and none says letters are ignored either. So write the letter for the person who opens it, and expect one of three form types: a file upload, a plain-text box, or no letter field at all.

For a file, go with the format the employer requests. If the choice is open, DOL's résumé advice calls a plain Word file the safest format for ATS compatibility. Its file-name advice covers letters too: name the file with your name and no spaces, as in AliciaThomas_coverletter. If you apply by email, DOL says to put your name, the position and the job reference number in the subject line and, if the instructions ask for a letter, to attach it separately.

One example, start to finish

Example (fictional) Tech. Sgt. Renee Alvarado, her employer and the hiring manager in this example are all fictional. She is an Air Force technical sergeant (E-6) who leaves active duty in January 2027. In October 2026 she finds a posting for an inventory control supervisor at Lakeshore Building Supply, a regional distributor. The posting asks for a résumé and a cover letter, in PDF or Word, and names Tomas Greer, the operations manager, as the hiring manager. A posting that asks for a letter settles the first question.

The posting wants experience supervising a warehouse team, accurate counts and inventory software. She has supervised and she has counted. The software is adjacent: she works in the Air Force's electronic supply system, not Lakeshore's. Her résumé leads with her supervision duties, so the letter tells a different story: a full inventory and the daily review that cut the wait for critical parts. She takes the numbers from her last evaluation and the award package for that project: 14 people, $9.2 million, 11,400 items, 6 days down to 4.

She writes the first draft the way she would write an evaluation line, then translates it. The result is the paragraph in the first figure. The posting names the hiring manager, so the letter opens "Dear Mr. Greer" and signs off "Sincerely," not V/R. Her finished letter, without the greeting and signature:

I am applying for the inventory control supervisor job at Lakeshore Building Supply, which I found on your careers page. I leave active duty in the U.S. Air Force in January 2027, and I want to keep working in supply and delivery. Your careers page says you deliver to contractors the same day, and accurate shelves are what make that possible. That is the work I know, and I would like to do it for you.

Your posting asks for experience supervising a warehouse team, accurate counts and inventory software. I have supervised a team of 14 people since 2022, and I train each new team member before they work alone. Every month I check our counts against our system records and track down each difference. I haven't used your software, but I work in an electronic inventory system every day to receive, store and issue stock. My résumé lists the details.

For four years I ran the parts warehouse for an Air Force logistics unit, supervising a team of 14 and responsible for $9.2 million in equipment and supplies. I led a full count of all 11,400 items on our shelves and started a daily review that cut the wait for critical parts from 6 days to 4. Running a team and a count like that is the work this job asks for.

I would welcome the chance to talk about how my experience fits your warehouse. I could start in February 2027. Thank you for your time and consideration. I look forward to hearing from you.

The four paragraphs come to 258 words, inside DOL's 250 to 400 and CareerOneStop's 200 to 400, and they fit on one page. The letter names her branch and says what she did. It doesn't name her base, her unit or any mission, and it holds nothing classified. Its details are a head count, a dollar value and a number of days. The posting takes PDF or Word. DOL's résumé advice calls a plain Word file the safest format for ATS compatibility, so she picks Word and saves it as ReneeAlvarado_coverletter.docx, with no spaces in the name.

She is still on active duty, so before she submits, she asks her command ethics official how the seeking-employment rules apply to Lakeshore. She applies from a personal email address. Air Force guidance says using government email for a job search needs her supervisor's permission.

The Cover Letter tool in a free OperationMOS account takes the employer and the job title, plus a résumé saved in your account or a fact you type, and the posting if you paste one, then uses AI to write a first draft that you edit before you download it. It takes pasted and typed text, not uploaded files.

This is general information about writing a job-application letter, not legal advice, and no letter guarantees an interview or a job. The Labor Department's free Employment Workshop participant guide covers cover letters on pages 58 to 63, with a sample for a veteran on page 194, and CareerOneStop's veterans pages are free. If you're still serving, your command ethics official can say how the seeking-employment rules apply to you.
