The British Army first experimented with light infantry in the French and Indian War, to counter the tactics used by the French-allied Native Americans. Along with secondment of regular infantry, several specialised units were raised (including Rogers' Rangers and the 80th Regiment of Light-Armed Foot), though most if not all had been disbanded by the middle of the 1760s. From 1770, all regular battalions were required to designate one of their ten companies a "Light Company", though their training in skirmishing was poor and inconsistent.
