Those men with the CB rating on their uniforms considered themselves Seabees that were doing underwater demolition. They did not call themselves "UDTs" or "Frogmen", but rather "Demolitioneers" reflecting where Lt. Cmdr. Kauffman had recruited them from, the CB dynamiting and demolition school. UDTs had to be of standard recruiting age, Seabees older could not volunteer. Mid-year 1945, in preparation for the cooler waters around Japan, a cold water training center was created. With it came a more demanding physical. Team 9 lost 70% of the team to this change. Postwar, MCB 7 was tasked with projects at the UDT training facility on St. Thomas, Virgin Islands see Notes Cold War When World War II ended the Cold War began. Seabee service during this period supported a broad spectrum of the national interest; nuclear testing, two wars, embassy security, space race, CIA, military communications, international relations, pure science, and Camp David. Postwar interlude: Siberia-China On V-J-Day CB 114 was in the Aleutians. In September 1945 the battalion sent a detachment to the USSR to build a Fleet Weather Central. It was located outside Petropavlovsk-Kamchatsky on the Kamchatka Peninsula. The original agreement gave the Seabees 3 weeks to complete the base. Upon arrival the Russians told them they had 10 days and were amazed it was done in 10. It was one of two that Stalin agreed to. V-J-Day brought about Operation Beleaguer and the repatriation of the Japanese Army from China. Elements of the 33rd CB Regiment were involved: CBs 83, 96, 122 and 32nd Special. These units landed at Tsingtao and Tangku in November 1945 attached to the 6th Marine Division. CB 42 and A Co. 33rd Special landed at Shanghai with Naval Advance Base Unit 13. With the war over, the ongoing discharge men eligible left only enough for one CB and the two CB Specials. The men were consolidated in the 96th with the other CBs decommissioned. In December the 96th started airfields at Tsingtao and Chinwangtao in support of III Marine Amphibious Corps operations. May 1946 CB III Marine Amphibious Corps was ordered to inactivate the 96th CB on 1 August. The 96th was transferred to the 4th Marines, 1st Marine Division and deactivated from them.
