The British Legion was the name of a British provincial regiment established during the American Revolutionary War, composed of British Loyalist American infantry and dragoons. It was colloquially known as Tarleton's Raiders, the Green Horse, and the Green Dragoons, after the British officer who led most of its day-to-day activities, Lieutenant Colonel Banastre Tarleton, and the green uniform coats of its officers. "Legion" was an 18th-century term for a military unit the size of a regiment, but consisting of infantry and cavalry, or infantry, cavalry, and artillery, all under one command, to make it more flexible for scouting or irregular operations than a regiment, which consisted of infantry or cavalry alone.
