The first team commanders were Cmdr. E.D. Brewster (CEC) UDT 1 and Lt. Crist (CEC) UDT 2. Both Teams were "provisional" totaling the 180 men Lt Crist had put together from the 7th NCR.They wore fatigues, life-vests and were expected to stay in boats like the NCDUs. At Kwajalein Fort Pierce protocol was changed. Adm.Turner ordered daylight recon, and Ensign Lewis F. Luehrs, Charp. Bill Acheson and the men with them wore swim trunks under their fatigues. They stripped down, spent 45 minutes in the water in broad daylight. Still wet and in their trunks they reported directly to Adm. Turner. He concluded what they had done was the only way to get accurate intel on submerged obstacles, reporting as much to Adm. Nimitz. At Engebi Cmdr. Brewster was wounded. The success of UDT-1 not following Fort Pierce protocol rewrote the UDT mission model and training regimen. Ens. Luehrs and Charp. Acheson were each awarded a Silver Star for their initiative. while unintentionally creating the UDT "naked warrior" image. Diving masks were uncommon in 1944 and some had tried using goggles at Kwajalein. They were a rare item in Hawaii so Lt. Crist and CB Chief Howard Roeder had requested supply get them. A fortuitous observation by one of the men spotted a magazine advertisement for diving masks. A priority dispatch was made to the States that appropriated the store's entire stock. The UDTs adopted google's independent of the OSS. When UDTs 1 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.
