The ten highest army ranks, from lowest to highest, are field marshal, general of the army, marshal of the air force, fleet admiral, marshal of the republic, five‑star general of the army, five‑star admiral of the fleet, five‑star marshal of the air force, five‑star general of the air force, and five‑star marshal of the republic.
Commonwealth and British‑derived ranks
In the United Kingdom and most Commonwealth nations, the top rank is field marshal in the army, marshal of the air force in the RAF, and admiral of the fleet in the navy. These are five‑star ranks and are rarely awarded, usually only in wartime or as ceremonial honours.
United States five‑star ranks
The U.S. created five‑star titles during World War II to match British counterparts. The titles are General of the Army, General of the Air Force, and Fleet Admiral. They were awarded to four senior officers and have not been used since the war.
French and other European equivalents
France awards the dignity of Maréchal de France (Marshal of France) and Amiral de France. These are state honours rather than career ranks and are granted by the President for exceptional wartime achievements.
Legal status and wartime use
Most five‑star ranks are reserved for wartime or are honorary. In democratic countries, they are explicitly limited by law to prevent permanent militarisation of the state. Peacetime armies normally use four‑star generals as the highest active rank.
Operational impact of the top ranks
When active, a five‑star officer commands entire theatres or joint services, advising the head of state and coordinating national strategy. Their authority extends beyond tactical units to national defence policy and international coalition leadership.
