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

Peru’s armed forces wear their rank in Spanish — and in gold. An officer’s grade is read from the gold bars and sun devices on the shoulder boards, a naval officer’s from the gold stripes on the sleeve, and a senior NCO’s from the chevrons on the sleeve. This guide covers every Peruvian military rank with its insignia, across the Army (Ejército del Perú), Navy (Marina de Guerra del Perú) and Air Force (Fuerza Aérea del Perú) — from Soldado to General de ejército.

Peruvian ranks follow the Spanish-language system inherited from Spain and shared across much of Latin America. The three services sit under the Joint Command of the Armed Forces (Comando Conjunto de las Fuerzas Armadas), but each keeps its own titles: an army captain is a Capitán, a naval captain is a Capitán de navío, and an air force lieutenant colonel is a Comandante.

Peru is not a NATO member, so the OF and OR grades below are NATO-style equivalents for comparison with US and European ranks — not NATO grades themselves.

Peruvian Army Ranks

The Peruvian Army is the largest of the three services, organised into military regions and responsible for land defence, border security and counter-insurgency operations, including in the VRAEM region. Its officer ladder runs from Subteniente to General de ejército, with a rarely conferred honorary rank — Gran Mariscal del Perú (Grand Marshal of Peru) — above them all at OF-10.

Peru uses a three-rank general system: there is no OF-6 brigadier general; the generals are General de brigada, General de división and General de ejército.

Peruvian Army Officer Ranks

Army officer insignia is worn on the shoulder boards or shirt collar. The rule is simple: junior and field officers are counted in gold bars, one for Subteniente rising to six for Coronel, while generals are counted in gold suns — the sun (sol), Peru’s great national symbol. Officer cadets hold the student rank of Cadete while training at the military academy.

Peruvian Army Enlisted and NCO Ranks

Army NCOs fall into two groups: the senior suboficiales (Suboficial primero, segundo and tercero), who train soldiers, run companies and advise officers, and the junior sargentos and cabo. A Soldado is a new recruit at the foot of the ladder.

Peruvian Navy Ranks

The Peruvian Navy (Marina de Guerra del Perú) defends Peru’s Pacific coast out to 200 nautical miles, and also operates on Lake Titicaca and in the Amazon basin, from its main base at Callao. It runs the Naval Infantry Force and the coast guard, with a fleet of frigates, corvettes, submarines and river gunboats.

Navy officers wear their rank as gold stripes on the lower sleeve, in the international naval pattern, with a broad stripe marking the senior grades. Above the active ladder sits the honorary rank of Gran Almirante del Perú — conferred posthumously on Admiral Miguel Grau, hero of the War of the Pacific, in 1967.

Peruvian Navy Officer Ranks

Naval titles are a trap for English speakers: a Capitán de navío is the equivalent of a full captain in the US Navy, not an army-style captain. The ship word — navío (ship of the line), fragata (frigate) or corbeta (corvette) — recalls the size of ship the rank once commanded, a legacy of the age of sail.

Peruvian Navy Enlisted and NCO Ranks

The two most junior sailors — Marinero and Grumete — wear no rank insignia at all. Grumete is an old Spanish naval word for a ship’s boy or apprentice, kept as the title of the navy’s newest recruits. Above them, the oficiales de mar are the senior enlisted sailors, the equivalent of chief petty officers, and the cabos are its petty officers.

Peruvian Air Force Ranks

The Peruvian Air Force (Fuerza Aérea del Perú) provides air defence and air-to-ground support from bases in the northern, central and southern regions, flying fighters, transports and helicopters, and carrying out border surveillance and airlift.

Its officer ranks follow the army’s pattern — gold bars for junior and field officers, gold suns for generals — but with two titles of its own: the lieutenant colonel equivalent is Comandante, and the most senior general is General del aire. The air force has no OF-10 rank and no OF-6 grade.

Peruvian Air Force Officer Ranks

Peruvian Air Force Enlisted and NCO Ranks

The air force’s enlisted ladder matches the army’s rank for rank, with only the lowest rank renamed: where the army has a Soldado, the air force has an Avionero, literally an “airman”. Air force officer cadets hold the student rank of Cadete F.A.P. while training.

Peruvian Technician Ranks

Between the NCOs and the commissioned officers, Peru has a third ladder with no direct US equivalent: the técnicos, or technicians. These career specialists — experts in maintenance, electronics, logistics and administration — hold warrant-officer-style grades of their own: six in the army and air force, five in the navy.

A senior technician can outrank every NCO without holding a commission.

Technicians are easily confused with suboficiales, since both are senior enlisted career personnel. The difference: a suboficial is a command figure, while a técnico is a specialist whose authority comes from technical mastery.

How to Read Peruvian Military Insignia

Three services use three systems, but each follows a single counting rule:

• Army and Air Force officers — count the gold bars, then the suns. One to six gold bars mark the ranks from Subteniente or Alférez (one bar) to Coronel (six bars); above that, gold suns count the generals — one, two, then three. More gold means more senior.
• Navy officers — count the gold stripes on the sleeve. Junior officers wear one or two narrow gold stripes, senior officers wear more, and admirals wear a broad gold stripe with narrower stripes above it. The broader and more numerous the braid, the higher the rank — the same idea navies use worldwide.
• Enlisted ranks — look at the sleeve chevrons. The senior NCOs, the suboficiales and oficiales de mar, wear the most elaborate sleeve insignia; the sargentos and cabos wear simpler chevrons; and the most junior sailors, the Marinero and Grumete, wear no rank insignia at all.
• Watch the service, not just the rank. The same Spanish word can mean different grades in different services: the air force’s Comandante (OF-4) has no army equivalent of that name, and a navy Capitán needs its ship word — de navío, de fragata or de corbeta — to be read correctly. Check the uniform first.
• There is no OF-6 in Peru. The general-officer ladder jumps from OF-5 (Coronel / Capitán de navío) straight to OF-7, so the most junior Peruvian general is already a two-star equivalent.

Peruvian Military Badges

Rank insignia shows a service member’s grade. Badges show what they are qualified to do: aviator wings for pilots, parachutist wings for airborne-qualified personnel, and specialist badges for divers and marksmen are worn on the chest or sleeve, separate from rank insignia. Each service also has its own cap badges, and the national coat of arms appears on formal and ceremonial dress.

The most distinctive Peruvian tradition is naval: Admiral Miguel Grau, commander of the ironclad Huáscar in the War of the Pacific, is honoured throughout the service, from the fleet flagship that bears his name to the posthumous rank of Gran Almirante del Perú conferred on him in 1967. For a Peruvian sailor, Grau’s name carries the same weight Nelson’s does for a British sailor.

How Promotion Works in the Peruvian Military

Promotion in the Peruvian armed forces is governed by military law and each service’s regulations, combining seniority, merit, training and vacancies. Officers begin as cadets at their service academy and are commissioned as Subteniente, Alférez de fragata or Alférez.

Advancement then generally requires a minimum time in each grade, completion of the professional courses set for that grade, a good record and an available vacancy; senior officers are selected by boards, and promotion to general or flag rank is a selective step few reach.

Enlisted personnel advance from Soldado, Grumete or Avionero through the junior NCO grades by time in service, conduct and training; the step into the senior NCO ranks — Suboficial tercero and above, or Oficial de mar tercero in the navy — is competitive, requiring courses and selection. Technicians advance through their own ladder on technical qualification and experience.

Exact time-in-grade requirements are set by Peruvian law and differ between the services, so the tables here show the order of ranks, not a fixed timetable.

A Note on Peruvian Military Tradition

Two things explain almost everything about Peruvian military ranks. The first is the Spanish inheritance: the titles, the three-rank general system and the sleeve-stripe navy come from the Spanish and French military traditions that shaped Latin America’s armies in the nineteenth century, which is why a Peruvian rank table reads so much like Spain’s or Argentina’s — and so differently from the US one.

The second is the sun: Peru’s generals wear gold suns rather than stars, a device from Peru’s own national symbolism, where the sun has stood for the country since the Inca era.

For comparison, see our guides to US Navy ranks, the US military uniform and the US military branches, and for another South American system see our guide to Brazilian military ranks.

FAQs

What is the highest rank in the Peruvian military?

The highest active rank is General de ejército (army), Almirante (navy) and General del aire (air force) — all OF-9 equivalents. Above them sit the honorary Gran Mariscal del Perú and Gran Almirante del Perú, rarely conferred; Gran Almirante was given posthumously to Admiral Miguel Grau in 1967. The air force has no OF-10 rank.

How many ranks are there in the Peruvian military?

Each service has 16 ranks in the main ladder: 7 enlisted ranks and 9 or 10 officers — the army and navy have 10 including their honorary supreme ranks, the air force 9. Each service also has a separate technician ladder of five or six grades.

What do Peruvian general officers wear as insignia?

Gold suns: one for the most junior general (General de brigada / Mayor general), two for the next (General de división / Teniente general) and three for the most senior (General de ejército / General del aire). Junior and field officers wear one to six gold bars instead.

What is the Peruvian equivalent of a US Navy captain?

Capitán de navío (OF-5). But beware the false friend: a Peruvian army Capitán is only OF-2. In the navy, the word after Capitán — de navío, de fragata or de corbeta — tells you the grade.

What rank is a Suboficial primero?

It is the most senior enlisted rank in the Peruvian Army and Air Force, the OR-9 equivalent of a US sergeant major. In the navy the equivalent is Oficial de mar primero.

Do the lowest Peruvian ranks wear insignia?

In the navy, no: a Marinero and a Grumete wear no rank insignia at all. In the army and air force, the entry-level Soldado and Avionero wear the plainest sleeve marking in their service.

What are técnicos in the Peruvian military?

Técnicos are career technical specialists who sit between the NCOs and the commissioned officers, in a ladder of their own — for example Técnico primero, segundo and tercero. They are the warrant-officer equivalent of the Peruvian system, and their authority comes from technical expertise, not command.
