Jaegers were very often (but not always!) armed with rifles, instead of the smooth-bore muskets of the bulk of the infantry. Rifles had better accuracy and longer range than muskets, but took longer to load. In most countries at the time, jaegers were usually attached in small groups to larger infantry formations for scouting and skirmishing. They had a hard time defending themselves in an all out battle because of the lower rate of fire, so relied on their line infantry counterparts to defend them. Many countries also used more conventional "light infantry", armed with muskets and operating in battalion or even brigade sized formations, who usually moved quicker than the line infantry and specialized in skirmishing, but the jaegers or riflemen were generally considered an elite amongst that elite. Roughly. Ok Steph, correct me.
