In September 1942, 17 Navy salvage personnel arrived at ATB Little Creek, Virginia for a week-long course in demolitions, explosive cable cutting, and commando raiding techniques. On 10 November 1942, the first combat demolition unit successfully cut cable and net barriers across the Wadi Sebou River during Operation Torch in North Africa. This enabled to traverse the water and insert U.S. Rangers who captured the Port Lyautey airdrome.
