Ms. Marianne Duchesne Department of Public Safety Darby Creek University Columbus, United States
Application for Armed Security Officer, Darby Creek University
Dear Ms. Duchesne,
I am applying for the Armed Security Officer post with the Darby Creek University Department of Public Safety. I hold an Ohio Department of Public Safety security guard identification card, number OH-SG-0418772, carrying a firearm-bearer notation that is current through August 2027, and I requalified on the range in November 2025. My posts have been contract distribution and retail, then three years on armed posts inside a 400-bed hospital.
The hospital work is the part that maps onto a campus. I cover the emergency department, the behavioral health unit and the ambulance bay, which runs to roughly 9 combative patient calls a week. I am certified in crisis prevention and physical intervention, and on that post a restraint is the last step of a documented escalation sequence rather than the first response, with the clinical team leading. I also reconcile about 120 contractor badges a month against the visitor log, and I trained 22 new officers on our campus post orders and signed off their first unsupervised shift.
I know your buildings. In 2022 I covered residence hall lobby posts at Darby Creek on relief for Buckeye Ridge, including the north quad over two winter breaks. I noticed the department expanded the late-night walking escort to seven nights this year, and that is the kind of post I would want to take on, alongside the armed exterior patrol the advertisement describes.
My card, my crisis intervention certification and my CPR, first aid and AED are all current, and I can work any shift pattern including nights and weekends. I can start within two weeks of an offer. Thank you for your time.
Sincerely, Darnell Whitaker
Summary
A security guard cover letter names the license you hold, whether it carries an armed endorsement, and the kind of post you have already covered. This guide gives you a full adaptable letter, the opening lines that work for a guarding account manager, and what changes when you write to an in-house employer instead of a contract firm.
Security Guard cover letter examples by experience level
A security guard cover letter is a one-page letter that tells the person filling a post three things: which state licensed you, whether your card lets you carry, and what kind of site you have already stood on.
Everything else is optional. Guarding is hired against a start date, often one inside the same week, and the reader is checking whether you can legally be assigned before they check whether they like you.
Guide to a security guard cover letter
This guide and the corresponding security guard cover letter example will cover:
- How to structure the letter, paragraph by paragraph
- Why the license and its endorsement belong in the first two sentences
- What counts as evidence when your work is a post rather than a project
- How the letter changes between a contract firm and an in-house employer
How to write a security guard cover letter
| Paragraph | Its job | Length |
|---|---|---|
| Opening | The post, your card, its endorsement and its expiry | 2 to 3 sentences |
| Evidence | One site, one volume, one period of time | 4 to 5 sentences |
| Fit | Something real about their site, and what you would cover | 3 to 4 sentences |
| Close | Certifications, availability, thank you | 2 sentences |
Put the card, the notation and the expiry in the first two sentences
Most states require security guards to be licensed by the state in which they work, and armed guards face additional licensing and more stringent background checks (U.S. Bureau of Labor Statistics, Occupational Outlook Handbook, last modified 27 August 2026).
So the first question in the reader's head is whether they can put you on a rota. Answer it before they ask: "I hold an Ohio Department of Public Safety security guard identification card, number OH-SG-0418772, with a firearm-bearer notation, current through August 2027 and requalified on the range in November 2025."
One sentence, and the file has cleared the one gate that closes it outright.

Openings that work
| Instead of | Use |
|---|---|
| I am writing to express my interest in your security position | I am applying for the Armed Security Officer post with the Department of Public Safety |
| I am a reliable and hardworking security professional | I hold an Ohio DPS card with a firearm-bearer notation, current through August 2027 |
| I have experience in various security settings | My posts have been contract distribution and retail, then three years on armed posts in a 400-bed hospital |
| I would be an asset to your team | In 2022 I covered residence hall lobby posts on your campus on relief |
The pattern is the same every time: replace a claim about your character with a fact the reader can verify in the state's license register or in their own site records.
What counts as evidence when your work is a post
Guarding produces almost nothing a recruiter can read afterwards. No portfolio, no sales figure. The evidence has to be the shape of the post itself.
| Kind of evidence | What it looks like in a sentence |
|---|---|
| Site scale | Sole night officer on a 140,000 square foot distribution center |
| Patrol tempo | Two exterior patrols an hour across a 12-hour shift |
| Call volume | Roughly 9 combative patient calls a week in the emergency department |
| Access control | About 120 contractor badges a month reconciled against the visitor log |
Pick two. A letter with five of these reads as a resume with the line breaks taken out.
Contract firms and in-house employers read differently
Writing to a contract guarding firm, lead on availability, shift flexibility and the number of post types you can cover, because the account manager is filling a rota across several clients. Writing to an in-house employer such as a hospital, a university or a corporate campus, lead on the post type you have already held and the training that matches it, because they are filling one post and will keep you in it. Name the site by type if a confidentiality clause stops you naming the client. Say plainly when you can start.
Do not send the same letter to both. Do not describe an incident in enough detail to identify a patient, a student or a member of the public. Do not claim a notation you have not been granted yet; say instead that the training is under way and give the date. Do not write more than one page, and do not open with a paragraph about your commitment to safety.
The pay gap you are writing yourself into
The median wage for security guards and gambling surveillance officers was $38,050 a year, or $18.29 an hour, as of May 2025, and about 157,200 openings are projected each year over the 2025 to 2035 decade (U.S. Bureau of Labor Statistics, Occupational Outlook Handbook, last modified 27 August 2026).
Within that one occupation, the median in healthcare and social assistance is $44,920 and in educational services it is $44,250, against $37,350 in investigation, guard and armored car services and $35,640 in retail trade (BLS, May 2025). Investigation, guard and armored car services employ 58% of all security guards; healthcare and education together employ about 13%.
The letter is not competing for a job. With 157,200 openings a year, a licensed applicant will find one. It is competing for the post type, and the sentence that moves you across names a site you have already held of the kind they are filling.
Length, format and sending it
One page, four paragraphs, 250 to 400 words. PDF unless the portal says otherwise, named for you and the post: darnell-whitaker-armed-security-officer-cover-letter.pdf.
Address a person. Directors of public safety, security managers and account managers are usually named on a site's own pages, and a letter specific about the post but vague about the reader reads as one sent to twelve firms.
Keep the numbers identical to the ones on your resume. Our security guard resume example uses the same figures, so the two files agree line by line.
Key takeaways
- Name the issuing state, the card number, the endorsement and the expiry in the opening.
- Give the date of your last range requalification if you are armed.
- Use two pieces of post evidence, not seven: a site scale and a volume.
- Say which post types you have covered, because that is what sets the pay band.
- Write differently to a contract firm than to an in-house employer.
- Name one real thing about their site, taken from their own pages.
- End with a start date and shift availability, not a restatement of interest.

Security guard cover letter questions, answered
How long should a security guard cover letter be?
One page, four paragraphs, 250 to 400 words. The reader is filling a post against a date, and a longer letter delays the two facts they need: your license status and your availability.
Do I need a cover letter if the guarding firm uses an online application?
Attach one wherever there is a field. The application collects the same structured answers from everyone. The letter is the only place to say which post types you have covered, which shifts you will take and when you can start, which is what the account manager sorts on.
What do I write if I am not licensed yet?
Say exactly where you are and name the board: application filed, training booked or completed, expected card date. Some employers sponsor applicants through licensing, and a letter that states the position plainly is stronger than one that avoids it and gets found out at the offer stage.
Should I mention pay expectations?
Not in the letter. Post type moves pay far more than negotiation does here: the median runs from $35,640 in retail trade to $44,920 in healthcare and social assistance for the same job title (BLS Occupational Outlook Handbook, May 2025 wage data). Spend the letter proving you fit the better post.
How do I write about an incident I handled?
Category, volume and outcome, never the person. "Roughly 9 combative patient calls a week, with restraint as the last step of a documented escalation sequence" shows your judgement without identifying anybody. A narrative about one dramatic night says less and creates a confidentiality problem you do not need.
