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 when they joined the UDTs. They were adopted by the other teams as quick 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. The last UDT operation of the war was on 4 July 1945 at Balikpapan, Borneo. The rapid demobilization at the conclusion of the war reduced the number of active duty UDTs to two on each coast with a complement of seven officers and 45 enlisted men each.
