British Commandos
In mid-1942, the United States Army formed its Army Rangers in Northern Ireland under William O. (Bill) Darby. The Rangers were designed along the similar lines to the British Commandos. The first sizable Ranger action took place in August 1942 at the Dieppe Raid, where 50 Rangers from the 1st Ranger Battalion were dispersed among Canadian regulars and British Commandos. The first full Ranger action took place in November 1942 during the invasion of Algiers in Northwest Africa in Operation Torch, again by members of the 1st Ranger Battalion.
