Argentine Military Ranks: Complete Guide to Ranks, Insignia and Badges (2026)

Argentina’s armed forces wear their history on their shoulders — quite literally. An Argentine Army officer’s rank is read from the golden suns on his shoulder boards, a naval officer’s from the gold braid stripes on his sleeve cuffs, and an air force officer’s from the stripes and stars on a sky-blue board. This guide covers every Argentine military rank with its insignia, from the newest volunteer soldier to the three-star generals and admirals who command the services, across the Army (Ejército Argentino), the Navy (Armada de la República Argentina) and the Air Force (Fuerza Aérea Argentina).

Argentina’s military is organised into three equal branches under the Joint Chiefs of Staff, with about 72,000 active personnel. The Army is the oldest service, founded on 29 May 1810 during the May Revolution; the Navy traces its birth to the same revolutionary year under the Irish-born Admiral Guillermo Brown; and the Air Force, founded in 1945, is the youngest branch.

All three use Spanish rank titles, and all three map onto the NATO OF (officer) and OR (other ranks) grading system, so an Argentine rank can be matched to its American or British equivalent at a glance.

One thing to know before reading the tables: Argentine ranks do not translate word for word. Teniente general sounds like “lieutenant general” but is the Army’s highest rank, equal to a full four-star general.

Comodoro in the Air Force means colonel, while Comodoro de marina in the Navy is a one-star flag distinction. And the Army has a rank most countries do not — Coronel mayor, senior colonel — sitting between colonel and brigadier general.

Argentine Army Officer Ranks (OF-9 to OF-D)

The Argentine Army has eleven officer ranks. Generals command at the top, senior officers (colonels and majors) run regiments and staffs, and junior officers lead platoons and companies. The highest rank in use is Teniente general, held by the Chief of the General Staff of the Army.

A higher rank, Capitán general (captain general), was awarded twice in the nineteenth century — to José de San Martín and Bernardino Rivadavia — but it is purely honorary and no insignia for it exists today.

How to Read Argentine Army Officer Insignia

Army officers wear their rank on shoulder boards, and the whole system is built around one national symbol — the Sun of May (Sol de Mayo), the golden sun from the Argentine flag. Once you know the sun-and-star code, any Argentine Army shoulder board reads at a glance:

• Suns for senior officers and generals — the number of suns counts down with seniority in the opposite direction from what you might expect at the top. A colonel wears three suns, a lieutenant colonel two, and a major one. Among the generals the count runs the other way: a brigade general wears two suns, a divisional general three, and a lieutenant general four.
• The red trim — shoulder boards from Coronel mayor upward carry a red (garnet) trim, and their suns are worked in gold braid rather than metal. That red edge is the fastest way to spot a general officer or senior colonel. Generals also wear golden laurel wreath leaves on their coat lapels.
• Stars for junior officers — below major, the suns give way to stars: three for a captain, two for a first lieutenant and one for a lieutenant. A sub-lieutenant, the rank held on graduation from the Colegio Militar de la Nación, wears a single star.
• The odd one out — Coronel mayor wears a single red-trimmed golden sun, where a regular colonel wears three plain suns. The rank is an official distinction, created in 1992, for long-serving colonels who have not been promoted to brigade general. It sits above colonel and below brigade general, and it is roughly equal to a brigadier general in the US system.
• Combat uniform — on campaign dress the same ranks appear as smaller collar insignia instead of shoulder boards, and volunteer soldiers wear their rank on the sleeve rather than the shoulder.

Argentine Navy Officer Ranks (OF-9 to OF-D)

The Argentine Navy’s officer ranks follow the Royal Navy tradition: rank is read from gold braid stripes on the sleeve cuffs, with the number and width of the stripes rising with seniority. The top stripe of a line officer carries the distinctive loop — the curled “executive curl” borrowed from the British Navy.

The Navy’s highest rank is Almirante (admiral), held by the Chief of the General Staff of the Navy. The Naval Infantry (marines) use the same ranks and insignia as the rest of the Navy.

How to Read Argentine Navy Officer Insignia

Navy rank is a counting exercise in gold braid. The rules are simple once you know them:

• Count the stripes — a corvette lieutenant wears one stripe, a ship lieutenant two, a frigate captain three and a ship-of-the-line captain four. Each step up adds a stripe until the flag ranks, where a wide stripe joins the pattern.
• The loop — the top stripe of a line (command) officer ends in a loop, the Royal Navy executive curl. It is the mark of an officer of the Command Corps, trained at the Escuela Naval Militar. Staff Corps officers — engineers, doctors, paymasters, chaplains and lawyers — wear their stripes on a coloured background that shows their speciality: purple for chaplains, blue for engineers, red for the health corps, white for paymasters and green for judge advocates.
• The commodore distinction — Comodoro de marina is not quite a normal rank. Created in the late 1990s, it is a distinction given to senior captains holding a rear admiral’s post, and it can be granted by the chief of staff without the congressional approval a flag promotion needs. Its sleeve lace matches the Royal Navy commodore’s, and it carries one star on the shoulder board.
• Where it is worn — stripes go on the sleeve cuffs of the dress uniform or on shoulder boards, and on the chest when officers are in shipboard or flying coveralls. Combat uniforms use metal pin-on or embroidered collar insignia instead.

Argentine Air Force Officer Ranks (OF-9 to OF-D)

The Air Force’s officer ranks use a mix of Army-style and Navy-style titles that is unique to Argentina. The general officers are all Brigadier of one kind or another, and the senior officers are Comodoro and Vicecomodoro — commodore titles that in most air forces would be a single rank.

The highest rank is Brigadier general, held by the Chief of the General Staff of the Air Force. Officers wear their rank as sleeve stripes, with matching shoulder boards in grey for ranks from ensign to commodore; general officers wear different shoulder boards of their own.

How to Read Argentine Air Force Officer Insignia

Air Force insignia is the youngest of the three systems, and it borrows from both sister services:

• Sleeve stripes, like the Navy — officers wear their rank in gold stripes on the sleeve, with the number of stripes rising with seniority. The same pattern is repeated on grey shoulder boards for ranks between ensign and commodore.
• Stars for the junior ranks — like the Army, the Air Force marks its junior officers with stars on the shoulder board: three for a captain, two for a first lieutenant and one for a lieutenant or ensign.
• Blue boards — Air Force rank insignia is gold on a bright blue shoulder board, against the Army’s green or black and the Navy’s dark blue. The colour alone tells you the service before you count a single stripe.
• The brigadier ladder — the three general ranks are all brigadiers: Brigadier (one star, OF-7), Brigadier mayor (OF-8) and Brigadier general (OF-9). Do not confuse Brigadier with the British brigadier, a colonel-level rank — in Argentina it is a general officer.
• The commodore trap — Comodoro in the Air Force equals a colonel (OF-5), while Comodoro de marina in the Navy is a one-star flag rank (OF-6). Same word, different ladder. The Air Force’s OF-6 equivalent is Comodoro mayor.

Argentine Enlisted and Non-Commissioned Officer Ranks (OR-9 to OR-1)

Below the officers, each branch has its own ladder of non-commissioned officers and enlisted personnel. The senior NCO ranks all begin with Suboficial (sub-officer), and the most senior — Suboficial mayor — is the equivalent of a sergeant major or master chief.

The Army and Air Force still use the old term Voluntario (volunteer) for their lowest ranks, a reminder that Argentina’s military has been all-volunteer since conscription ended in 1995. The Navy instead uses Marinero (seaman).

How to Read Argentine Enlisted Insignia

Enlisted insignia is worn on the sleeve in the Army and Air Force, and on shoulder boards, breast patches or sleeves in the Navy, depending on the uniform. The pattern is the same in all three branches: more chevrons and more elaborate devices mean more seniority. Senior sub-officers wear distinctive insignia that set them apart from the sergeants and corporals below them, and the lowest ranks — volunteers and seamen — wear simple sleeve insignia with no chevrons at all.

Two details help in telling the branches apart. First, the words: only the Navy uses Marinero, only the Army and Air Force use Voluntario, and the Air Force is the only branch with Suboficial ayudante and Suboficial auxiliar in the middle of its ladder.

Second, the colour of the backing: Army insignia sits on green or black, Air Force insignia on bright blue. Navy other ranks wear their insignia on dark blue, and seamen wear theirs on the sleeve.

Argentine Military Badges and Emblems

Rank insignia shows a person’s grade. Badges show what they are qualified to do, and Argentina’s are rich in national symbolism:

• The Sun of May (Sol de Mayo) — the golden sun with a face and alternating straight and wavy rays, taken from the national flag. It is the defining mark of Argentine Army officer rank, and it appears on the national cockade and the presidential sash. It represents the Inca sun god Inti and the May Revolution of 1810.
• The naval anchor — the fouled anchor of the Armada, worn as a branch badge by sailors and naval officers, recalling the Navy’s founding under Admiral Guillermo Brown, the Irish-born “father of the Argentine Navy”.
• Air Force wings — pilot and aircrew wings are worn on the chest by qualified air force personnel, with the condor — the great bird of the Andes — featuring in the service emblem.
• Specialist and qualification badges — paratrooper wings, mountain troops badges, commando qualification and the Antarctic service badge mark the Army’s specialist units, including the mountain brigades of the Andes and the personnel who support Argentina’s Antarctic bases.
• Unit and branch insignia — each regiment, naval command and air brigade carries its own shield and colours, and Army officers wear branch-coloured backing on their shoulder boards showing their arm or service, such as infantry, cavalry, artillery or engineers.

How Promotion Works in the Argentine Military

Promotion in Argentina is a mix of time in grade, courses and selection. Officers enter through their branch academy — the Colegio Militar de la Nación for the Army, the Escuela Naval Militar for the Navy and the Escuela de Aviación Militar for the Air Force — and graduate as sub-lieutenant, midshipman or ensign. Junior officers then advance roughly every four to five years through the lieutenant and captain grades, as long as they complete the required courses and hold good records.

Promotion to the senior ranks is competitive and selective. Officers must pass staff college and command courses, and the choice of who becomes a colonel, a general or an admiral is made by senior boards and confirmed at the highest level: promotions to general and flag rank require the agreement of the Senate, as the constitution gives Congress a role in senior military appointments.

Enlisted personnel enter as volunteers or seamen and climb the ladder from corporal to sergeant to sub-officer through trade courses, time in grade and selection boards. The most senior NCOs — the Suboficial mayor of each service — act as the enlisted voice to their chief of staff. Since Argentina ended conscription in 1995, every rank from volunteer upward is filled by professional volunteers.

A Note on Argentine Military Tradition

Two threads run through everything about Argentine military ranks. The first is independence: the Army was born in the May Revolution of 1810, the sun on its shoulder boards is the sun of the May flag, and the highest honorary rank belongs to José de San Martín, the Liberator of Argentina, Chile and Peru.

The second is European heritage with a local accent: the Navy’s sleeve stripes and executive curl come from the Royal Navy, the Army’s shoulder boards and suns from the Spanish tradition, and the Air Force’s brigadier and commodore titles from Britain — yet the combination is unmistakably Argentine.

FAQs

What is the highest rank in the Argentine military?

In the Army it is Teniente general (OF-9), in the Navy Almirante (OF-9) and in the Air Force Brigadier general (OF-9). Each is held by the chief of staff of its service.

The highest enlisted rank in all three branches is Suboficial mayor (OR-9). There is no five-star or OF-10 rank in Argentina.

What is a Coronel mayor?

Coronel mayor (senior colonel, OF-6) is an official distinction created in 1992 for long-serving colonels who have not been promoted to brigade general. It sits between colonel and brigade general, and its insignia — a single golden sun on a red-trimmed shoulder board — looks like a general’s board, which is why it confuses newcomers. Its Navy equivalent is Comodoro de marina and its Air Force equivalent is Comodoro mayor.

Why do Argentine Army officers wear suns?

The suns are the Sun of May (Sol de Mayo), the golden sun from the Argentine flag, representing the May Revolution of 1810. Generals and senior officers are read by the number of suns on their shoulder boards, while junior officers are read by stars. The red trim on boards from senior colonel upward marks the general-officer style.

Is an Air Force Comodoro the same as a Navy Comodoro de marina?

No. An Air Force Comodoro is OF-5, the equivalent of an Army colonel. A Navy Comodoro de marina is OF-6, a one-star flag distinction for senior captains in flag appointments.

The Air Force’s OF-6 equivalent is Comodoro mayor.

Do Argentine ranks have NATO equivalents?

Yes. Argentina uses the NATO OF/OR grading system: officers run OF-D (sub-lieutenant, midshipman, ensign) to OF-9 (lieutenant general, admiral, brigadier general), and enlisted personnel run OR-1 to OR-9. That makes it straightforward to match an Argentine rank with its US or British equivalent.

What is the lowest rank in the Argentine military?

The lowest ranks are Soldado de segunda en comisión in the Army, Marinero segundo in the Navy and Voluntario segundo in the Air Force — all OR-1, the entry level for new volunteers.
