legionaries

Legionary is a term for a soldier serving in a legion, a large military unit historically associated with the Roman army. In broad use, “legionary” can apply to members of any unit labeled a legion, but the term most commonly refers to Roman infantrymen trained and deployed by the Republic and later the Empire.

Roman legionaries were professional infantrymen in the Roman Republic and Empire. A legion contained around 4,500–6,000 infantry and supporting cavalry, organized into cohorts and further into centuries led by centurions. Typical equipment included the lorica segmentata or chain mail, a helmet, the oval shield scutum, the gladius sword, and the pilum spear. They trained extensively, served long terms, and were often veterans granted land or pensions after discharge. Duties included conquest, siege warfare, and frontier garrison; they also built roads, fortifications, and in many regions contributed to local administration.

With the decline of the Western Roman Empire, the term persisted in historical and later military contexts. In modern times, “legionary” remains a generic term for soldiers serving in legions, and is most widely associated with the French Foreign Legion.

The French Foreign Legion, established in 1831, is a major modern example. It accepts volunteers from many nations, operates under a distinct code, and provides its own recruit training, rapid deployment capability, and a career path within the French Army. Legionaries serve under contract terms, may receive French citizenship, and are organized with non-commissioned and commissioned officers. The unit is known for its international composition and seasoned expeditionary role within French foreign policy.
