The oldest was the TTU organization of the Phib Tra Pac established originally on 15 August 1943 to prepare Army as well as Navy and Marine forces for amphibious operations. After making a distinguished record in World War II, TTU created a permanent place for itself during the following five years.[9] [9] Joint Landing Force Board, Project No. 13-52, Annex Able, 28–30; see also FMFPac, _Historical Outline of the Development of FMFPac 1941–1950_ (Preliminary), 15–16 (hereafter, FMFPac _History_); and Maj Gen W. S. Fellers memo to authors, 16 Feb. 55. A group of TTU officers and enlisted men under the command of Colonel Forney made up Mobile Training Team Able in the spring of 1950. Sailing from San Diego in April, these Marines were accompanied by a second group of amphibious specialists, the ANGLICO (Air and Naval Gunfire Liaison Company) instruction team commanded by Lieutenant Edward B. Williams, USN.[10] [10] Capt E. P. Stamford interv with HistDiv HQMC, 16 Mar 51. The ANGLICOs, composed of both Navy and Marine Corps personnel, evolved in 1949 to assist Army units lacking the forward air control and naval gunfire control units which are integral in Marine divisions. Growing out of the responsibility of the Marine Corps for the development of those phases of landing force operations pertaining to tactics, techniques, and equipment employed by landing forces, the first company was formed in answer to the request of Lieutenant General Mark W. Clark, USA, for a unit capable of giving an Army division this sort of amphibious fire support. After taking part in the MIKI exercises with the Sixth Army in Hawaii during the autumn of 1949, this ANGLICO split up into instruction teams assigned to various Army units.[11] [11] _Ibid._ The amphibious functions of the Marine Corps, as outlined by National Security Act of 1947 and the Key West Conference of 1948, are discussed in the following chapter. Training Team Able and Lieutenant Williams’ ANGLICO team reached Japan just in time to cooperate with a third organization of amphibious specialists, Rear Admiral James H. Doyle’s Amphibious Group (PhibGru) One of the Pacific Fleet. The three teams were given a mission of training one regiment from each of the four Eighth Army divisions in Japan. But the instruction program had only been launched when it was interrupted by the Korean conflict. PhibGru One and the ANGLICO team were immediately assigned to new duties in connection with the sea lift of Eighth Army troops to Korea. They had just begun this task when orders came for Admiral Doyle and his staff, in the USS _Mount McKinley_ at Sasebo, to proceed by air on 4 July to the conference at Tokyo.[12] There at FECOM Headquarters, they met General Fellers, Colonel Forney, and the Army officers who had been summoned from the Independence Day celebration of the American colony.
