Jäger (German: [ˈjɛːɡɐ]; German for 'hunter'; sg. [der] Jäger, pl. [die] Jäger) is a German military term referring to specific light infantry units. In German-speaking states during the early modern era, the term jäger came to denote light infantrymen whose civilian occupations (mostly hunters and foresters) made them well-suited to patrolling and skirmishing, on an individual and independent basis, rather than as part of a large-scale military unit or traditional line infantry. As a consequence, jäger was used to describe skirmishers, scouts, sharpshooters and runners. .
