Rogers' Rangers was an Independent Company of Rangers attached to the British Army during the French and Indian War. The unit was informally trained by Major Robert Rogers as a rapidly deployable Light Infantry force tasked with reconnaissance and conducting special operations against distant targets. Their military tactics were so bold and effective that the unit became the chief scouting unit of British Crown forces in the late 1750s. Later, several members of Rogers' Rangers became influential leaders in the American Revolutionary War and a large number of ex-rangers were present as patriot militiamen at the Battle of Concord Bridge
