Rogers' Rangers is initially a provincial company from the colony of New Hampshire, attached to the British Army during the Seven Years' War (called the French and Indian War in the United States).

The unit is quickly adopted into the British army as an independent ranger company.

It had been trained by Major Robert Rogers as a rapidly deployed light infantry force tasked mainly with reconnaissance as well as conducting special operations against distant targets.

Their tactics are built on earlier colonial precedents and are codified for the first time by Rogers.

The tactics prove remarkably effective, so much so that the initial company is expanded into a ranging corps of more than a dozen companies (containing as many as twelve hundred to fourteen hundred men at its peak).

The ranger corps becomes the chief scouting arm of British Crown forces by the late 1750s.

The British value them highly for gathering intelligence about the enemy.

The company is later revived as a Loyalist force during the American Revolutionary War.

Nonetheless, a number of former ranger officers become Patriot commanders.

Some ex-rangers participate as patriot militiamen at the Battle of Concord Bridge.

The Queen's York Rangers (1st American Regiment) of the Canadian Army, formed by Rogers and Loyalist veterans of Rogers' Rangers, claims descent from Rogers' Rangers.
