The Battle of Luzon, fought 9 January – 15 August 1945, was a land battle of the Pacific Theater of Operations of World War II by the Allied forces of the U.S., its colony the Philippines, and allies against forces of the Empire of Japan.

 The Allies had taken control of all strategically and economically important locations of Luzon by March 1945, although pockets of Japanese resistance held out in the mountains until the unconditional surrender of Japan.
 While not the highest in U.S. casualties, it is the highest net casualty battle U.S. forces fought in World War II, with 192,000 to 205,000 Japanese combatants dead (mostly from starvation and disease), 10,000 American combatants killed, and between 120,000 to 140,000 Filipino civilians and combatants killed.
Iwo Jima is a turn-based strategy video game developed and published by Personal Software Services for the Commodore 64 and ZX Spectrum in 1986.

USS "Iwo Jima" (LPH-2) was the lead ship of her class and type—the first ship to be designed and built from the keel up as an amphibious assault ship.
 She carried helicopters and a detachment of embarked Marines for use in the Navy's "vertical envelopment" concept of amphibious operations.
 "Iwo Jima" was the second of three ships of the United States Navy to be named for the Battle of Iwo Jima, although the first to be completed and see service (the first was cancelled during construction).
Iwo To (硫黄島 , Iō-tō , "sulfur island") , known in English as Iwo Jima (    ), is an island of the Japanese Volcano Islands chain south of the Ogasawara Islands and together with them forms the Ogasawara Archipelago also known as the Bonin Islands.
 The island of 21 km (8 square miles) is 1200 km south of mainland Tokyo and is administered as part of Ogasawara, one of the eight villages of Tokyo inhabited only by Japan Self-Defense Forces and used by the U.S. Navy for carrier practice.
 It was the setting of the February–March 1945 Battle of Iwo Jima involving the United States and a small number of elements of the British Pacific Fleet versus the Empire of Japan during World War II.
 The island grew in recognition outside Japan when the photograph "Raising the Flag on Iwo Jima" was taken on Mount Suribachi, the highest point at 160 metres (528 feet), during the battle by Associated Press photographer Joe Rosenthal.
 The U.S. occupied Iwo Jima until 1968 when it was returned to Japan.

The Battle of Iwo Jima (19 February – 26 March 1945) was a major battle in which the United States Marine Corps landed on and eventually captured the island of Iwo Jima from the Imperial Japanese Army during World War II.
 The American invasion, designated Operation Detachment, had the goal of capturing the entire island, including the three Japanese-controlled airfields (including the South Field and the Central Field), to provide a staging area for attacks on the Japanese main islands.
 This five-week battle comprised some of the fiercest and bloodiest fighting of the Pacific War of World War II.
South Field was a World War II airfield on Iwo Jima in the Volcano Islands, located in the Central Pacific.
 The Volcano Islands are part of Japan.
 The airfield was located on the southern corner of Iwo Jima located on the Motoyama plateau, to the north of Mount Suribachi.
 South Field was significant to the overall Battle of Iwo Jima.
