A Navy Mustang is a commissioned officer in the U.S. Navy who rose up from the enlisted ranks, earning a commission through an in-service program rather than the Naval Academy or ROTC. Their motto is Sursum ab Ordine — “up from the ranks.” Their creed: “I did it the hard way. I earned it!”
What Is a Navy Mustang?
A Navy Mustang is an officer who served as an enlisted Sailor first and was later commissioned without a break in active-duty service. The term is used across the sea services, and most commonly describes officers commissioned through the Limited Duty Officer (LDO) and Chief Warrant Officer (CWO) programs.
Other in-service commissioning paths that produce Mustangs include:
- LDO (Limited Duty Officer): technical specialists commissioned from senior enlisted ranks
- CWO (Chief Warrant Officer): warrant-grade technical experts
- STA-21 (Seaman to Admiral–21): enlisted Sailors sent to earn a degree and commission
- MECP (Medical Enlisted Commissioning Program): enlisted Sailors commissioning as nurses
- Fleet accession to OCS: Sailors selected for Officer Candidate School from the fleet
Prior-enlisted officers with sufficient enlisted service are paid at the O-1E, O-2E, and O-3E grades (the “E” marking prior enlisted time). It is a small but visible acknowledgement that they came up the hard way.
What sets a Mustang apart is not rank. It is that they have stood every watch they now assign. A Mustang division officer has swabbed the deck they are inspecting, and every Sailor in that division knows it.
What Does “Sursum Ab Ordine” Mean?
Sursum ab Ordine is Latin for “up from the ranks.” It is the unofficial motto of the Navy Mustang community, and it appears on Mustang challenge coins, plaques, and belt buckles throughout the fleet.
The phrase draws a deliberate line between Mustangs and officers commissioned directly from the U.S. Naval Academy, NROTC, the Merchant Marine Academy, or civilian-entry Officer Candidate School. It is not a claim of superiority. It is a statement of route. The commission was earned on the deckplates before it was earned in a classroom.
You will see it styled several ways in the fleet: Sursum ab Ordine, Sursum Ab Ordine, and occasionally run together as Sursum Abordine. All refer to the same motto.
The Navy Mustang Creed
The creed a Mustang Officer recites on receiving their commission is short enough to fit on a coin:
“I did it the hard way. I earned it!”
Six words carrying a decade or more of enlisted service. It is frequently paired with the Sursum ab Ordine motto on commissioning gifts, retirement shadow boxes, and Mustang Association memorabilia: the two lines together are the community’s shorthand for the whole journey.
Why Are They Called Mustangs?
The name comes from the horse, and the comparison is pointed.
One account traces it to the U.S. Naval Academy, where “thoroughbreds” meant officers bred through the traditional academy pipeline, and “mustangs” meant those who came up from the enlisted ranks. The term is relatively modern, appearing just before or during World War II, when the Navy’s surging need for technically capable officers pushed large numbers of qualified enlisted men into warrant and commissioned grades.
A mustang can be saddle-broken, the saying goes, but it keeps a wild streak. And because it ran free first, it may be tougher, smarter, and better at surviving rough conditions than a thoroughbred that was pampered its whole life. Within the community, the name is worn as a compliment.
The Limited Duty Officer program was formally codified in 1948, with the first LDO commissions taking effect the following year, turning an ad-hoc wartime practice into a permanent career path.
LDO vs. CWO and Who Counts as a Mustang?
This is genuinely debated in the fleet, and it is worth being straight about it.
The narrow definition: only LDOs and CWOs are true Mustangs, because those boards select specifically on combined enlisted leadership and technical ability. Purists in the LDO/CWO community hold this line firmly.
The broad definition: any officer commissioned from prior enlisted service without a break in service (LDO, CWO, STA-21, MECP, or fleet OCS) is a Mustang. The Navy Mustang Association generally recognizes officers commissioned without a break in service.
The practical difference between LDO and CWO: an LDO is considered more the officer and less the technician; a CWO is the deeper technical specialist. Both are assigned within the designator they came from, and both draw directly on their enlisted rating expertise.
The Navy Mustang Emblem
There is no single official Mustang insignia, the community’s visual identity is built from recurring elements rather than a regulated device. Designs almost always include some combination of:
- A mustang horse, usually rearing or in profile
- The motto Sursum ab Ordine, typically on a banner or ring
- “U.S. NAVY MUSTANG” lettering
- Fouled anchors, and occasionally the LDO or CWO device
- Navy blue and gold as the standard color pairing
Because nothing is prescribed, Mustang coins and buckles are almost always custom work — which is why commands, Mustang Associations, and individual officers commission their own.
About This Custom Navy Mustang Belt Buckle
A U.S. Navy Mustang came to Embleholics wanting the motto made physical: Sursum ab Ordine inscribed on a custom belt buckle, with an embossed mustang as the central graphic.
The brief was restraint. The buckle is an oval with the left and right edges cut flat, finished in gold plating over a navy blue background, with minimal ornamentation. No crowding, no competing elements. Just the horse, the motto, and clean negative space. A bold, simple design suits the Mustang ethos better than something ornate would.

Frequently Asked Questions
What is a Navy Mustang?
A Navy Mustang is a commissioned officer who previously served as an enlisted Sailor and earned their commission through an in-service program rather than the Naval Academy or ROTC. Most commonly they are Limited Duty Officers (LDO) or Chief Warrant Officers (CWO).
What does Sursum Ab Ordine mean?
Sursum ab Ordine is Latin for “up from the ranks.” It is the unofficial motto of the U.S. Navy Mustang community and appears on most Mustang coins, buckles, and plaques.
What is the Navy Mustang creed?
The creed recited by a Mustang Officer upon commissioning is: “I did it the hard way. I earned it!”
Why are prior enlisted officers called Mustangs?
The term contrasts the mustang (a formerly wild horse that is tough, self-reliant, and never fully tamed) with the “thoroughbred” officer commissioned straight from an academy. It dates to around World War II.
Is an LDO a Mustang?
Yes. Limited Duty Officers are the most widely recognized Mustangs, along with Chief Warrant Officers, since both are selected specifically on enlisted leadership and technical expertise.
What is the difference between an LDO and a CWO?
Both are commissioned from the enlisted ranks. An LDO functions more as a generalist officer within their designator, while a CWO remains the deeper technical specialist in their field.
Does STA-21 make you a Mustang?
It depends who you ask. Under the broad definition, any officer commissioned from enlisted service without a break in service is a Mustang. Under the narrow definition held by many in the LDO/CWO community, only LDO and CWO selectees qualify.
What does O-1E mean?
The “E” indicates a commissioned officer with qualifying prior enlisted service. O-1E, O-2E, and O-3E carry higher pay than their non-prior counterparts, recognizing time already served.
Are there Mustangs in the Marine Corps?
Yes. The Marine Corps has its own Mustang tradition and its own Mustang Association, and the term is used the same way, an officer commissioned up from the enlisted ranks.
What is the Navy Mustang Association?
The Navy Mustang Association is a membership organization for current, former, and retired Mustang officers, offering scholarships and connecting the community. It is independent of the U.S. Navy.
What goes on a Navy Mustang belt buckle?
Most include a mustang horse, the Sursum ab Ordine motto, “U.S. Navy Mustang” lettering, and often a fouled anchor or the LDO/CWO device. Because there is no regulated Mustang insignia, designs are custom.
Can I wear a custom belt buckle with a Navy uniform?
Buckle wear is governed by Navy uniform regulations, which specify authorized devices by uniform type. Check current uniform regulations or your command before wearing a custom buckle in uniform. Most custom Mustang buckles are worn with civilian attire, given as commissioning or retirement gifts, or displayed in a shadow box.
Do you make Navy Mustang challenge coins as well as buckles?
Yes. We produce Mustang challenge coins, belt buckles, bottle openers, and keychains, all with free artwork and unlimited revisions before production.
