South East Asia Command
Asiatic-Pacific Theater was the theater of operations of U.S. forces during World War II in the Pacific War during 1941–1945. From mid-1942 until the end of the war in 1945, there were two U.S. operational commands in the Pacific. The Pacific Ocean Areas (POA), divided into the Central Pacific Area, the North Pacific Area and the South Pacific Area, were commanded by Fleet Admiral Chester W. Nimitz, Commander-in-Chief Pacific Ocean Areas. The South West Pacific Area (SWPA) was commanded by General of the Army Douglas MacArthur, Supreme Allied Commander South West Pacific Area. During 1945, the United States added the  United States Strategic Air Forces in the Pacific, commanded by General Carl A. Spaatz.
Because of the complementary roles of the
United States Army and the United States Navy in conducting war in the Pacific Theater, there was no single Allied or U.S. commander (comparable to General of the Army Dwight D. Eisenhower in the European Theater of Operations). There was no actual command; rather, the Asiatic-Pacific Theater was divided into SWPA, POA, and other forces and theaters, such as the China Burma India Theater.

or the Philippine Islands as the next operational target in the Pacific theater.
^ Note that the Battle of Leyte Gulf is listed in both the Central Pacific Area (under Nimitz) and in the South West Pacific Area (under MacArthur). Leyte Gulf is where Nimitz's western thrust across the central Pacific Ocean intersected MacArthur's northern thrust across the western Pacific Ocean. While the Pacific Ocean command structure was convoluted, operations were "designed to sequence the SWPA's operations with POA's forces across the central Pacific. The main purpose of sequencing is to arrange objectives/tasks in such a progression that collectively they lead to the accomplishment of the assigned ultimate objective in the shortest time possible and with the least loss of personnel and materiel." Nimitz provided, but maintained control over, Admiral
Halsey's Third Fleet to cover and support Admiral Kinkaid's Seventh Fleet operating under General MacArthur. The result of this imprecise arrangement was the crisis precipitating the Battle off Samar. Halsey was operating under Commander in Chief, Pacific Operating Area's (Nimitz') Operations Plan 8–44.
^ By US Navy's Third Fleet under Admirals Halsey and Nimitz.
^ By US Navy's Task Force 38 under Admirals
Mitscher and Nimitz.
