U.S. military". Even though they are "Navy" the Seabees adopted USMC fatigues with a Seabee insignia in place of the EGA. At least 10 CB units incorporated USMC insignia into theirs. Admiral Moreell wrote, tongue in cheek, that the Marines were the best fighting men in the Pacific, but one had to serve 90 days with the Seabees to qualify to as a "Junior Bee". Naval Combat Demolition Units In early May 1943, a two-phase "Naval Demolition Project" was ordered by the Chief of Naval Operations "to meet a present and urgent requirement" for the invasion of Sicily. Phase-1 began at Amphibious Training Base (ATB) Solomons, Maryland with the creation of Operational Naval Demolition Unit # 1. Six Officers led by Lt. Fred Wise CEC and eighteen enlisted reported from Camp Peary dynamiting and demolition school. Seabees called them "Demolitioneers". Naval Combat Demolition Units (NCDUs) consisted of one junior CEC officer, five enlisted, and were numbered 1–216. After that first group had been trained, Lt. Commander Draper Kauffman was selected to command the program. It had been set up in Camp Peary's "Area E"(explosives) at the dynamiting and demolition school. Between May and mid-July, the first six NCDU classes graduated at Camp Peary. While the program was at Camp Peary the men were given head-of-the-line privileges at the mess hall. The program was moved to Fort Pierce where the first class began mid-July. Despite the move, Camp Peary remained Kauffman's primary recruit center. "He would go back to the dynamite school, assemble the (Seabees) in the auditorium and say, "I need volunteers for hazardous, prolonged and distant duty." Fort Pierce had two CB units assigned, CBD 1011 and CBMU 570. They were tasked with the construction and maintenance of obstacles needed for demolition training. The invasion of Normandy had 34 NCDUs. When the first ten arrived in England they had no CO. Lt. Smith (CEC) assumed the role, splitting them up to train with the 146th, 277th and 299th Combat Engineers. As more NCDUs arrived they did the same, with 5 combat engineers attached to each NCDU. Group III (Lt. Smith) did research and development and is credited with developing the Hagensen Pack. NCDUs had a 53% casualty rate at Normandy. Four from Utah beach later took part in Operation Dragoon. With Europe invaded, Admiral Turner requisitioned all available NCDUs from Fort Pierce for integration into the UDTs for the
