and 2 returned to Hawaii Chief Acheson and three other UDT Officers were transferred to the 301st dredging CB. The 301st had 12 dredges saving Teams from blasting channels, but needed divers to get the job done. Ensign Leuhrs made Lt. and was a member of UDT 3 until he was made XO of team 18. Commander Brewster's purple heart got him out of the UDTs and elevated to Commander 7th NCR instead of back to CB 10. Adm. Turner also requested the formation of a Demolition Training Center at Kihei. It was approved. The actions of UDT 1 provided the training model, making UDT training distinctly different from Fort Pierce's NCDU program. Lt. Crist was briefly the first training officer and emphasized swimming and recon until he was made CO of UDT 3. When UDT 3 returned from Leyte in the fall of 1944 it became the school instructors with Lt. Crist again OIC of training. The classes now included: night ops, weapons, bivouacking, small unit tactics, along with coral and lava blasting. In April 1945, team 3 was sent to Fort Priece to instruct there. Lt. Crist was promoted to Lt. Cmdr. and sent back to Kihei. Team 3 would train teams 12–22. UDT 14 is called the first "all fleet team" even though it had Seabees from Team Able and the CO and XO were both CEC. UDT 15 was the last team formed of NCDUs. Teams 12–15 were sent to Iwo Jima. Three cleared the shoreline for five days, D+2-D+7. After July 1944 new UDTs were only USN. In 1945, CBMU 570 was tasked to the UDT coldwater training center at ATB Oceanside, CA. On Guam team 8 requested permission to build a base. It was approved by AdComPhibsPac, but disapproved by Island Command. Team 8 turned to the CBs on the island and got everything needed. Coral paving got placed the night before Admiral Nimitz inspected, giving teams 8 & 10 a glowing review. By V-J day 34 teams had been formed. Teams 1–21 saw actual deployment with the Seabees providing over half of the men in those teams. The Navy did not publicize the existence of the UDTs until post-war and when they did they gave credit to Lt. Cmdr. Kauffman and the Seabees. During World War II the Navy did not have a rating for the UDTs nor did they have an insignia.
