in their trunks. Admiral Turner concluded that daylight reconnaissance by individual swimmers was the way to get accurate information on coral and underwater obstacles for upcoming landings. This is what he reported to Admiral Nimitz. The success of those UDT 1 Seabees not following Fort Pierce protocol rewrote the UDT mission model and training regimen. Those Seabees also created the image of UDTs as the "naked warriors". At Engebi CDR Brewster was wounded and all of the men with ENS Luehrs wore swim trunks under their greens. After the operations in the Marshall Islands, Admiral Turner restructured the two provisional UDT units and created 7 permanent units with an allotted size of 96 men per team. In the name of operational efficiency, the UDTs were also made an-all Navy outfit, and any Army and Marine corp engineers were returned to their units. Moving forward, the UDTs would employ the reconnaissance method made successful in Kwajalein - daytime use of swimsuits and goggles instead of the Scouts and Raiders method of nighttime rubber boats. In order to implement these changes and grow the UDTs, Koehler was made the commanding officer of the Naval Combat Demolition Training and Experimental Base on Maui. Admiral Turner also brought on LCDR Draper Kauffman as a combat officer. Seabees made up the vast majority of the men in teams 1–9, 13, and 15. Seabees were roughly 20% of UDT 11. The officers were mostly CEC. At war's end 34 teams had been formed with teams 1–21 having actually been deployed. The Seabees provided over half of the men in the teams that saw service. The UDT uniform had transitioned from the combat fatigues of the NCDUs to trunks, swimfins, diving masks and Ka-bars. The men trained by the OSS had brought their swimfins with them when they joined the UDTs. They were adopted by the other teams as quickly as Supply could get them. These "Naked Warriors", as they came to be called post-war, saw action in every major Pacific amphibious landing including: Eniwetok, Saipan, Kwajalein, Tinian, Guam, Angaur, Ulithi, Peleliu, Leyte, Lingayen Gulf, Zambales, Iwo Jima, Okinawa, Labuan, and Brunei Bay. By fall of 1944, the UDT's were considered an indispensable US military special operations unit, and Navy planners in the Central Pacific relied heavily on the UDT's reconnaissance reports and demolition activities to clear the way for landings. The last UDT operation of the
