Operation Flintlock was the campaign against the Japanese in the Marshall Islands in the Pacific theatre of World War II, from 31 January to 4 February 1944.
 The operation involved the invasions of Kwajalein, Eniwetok, and Majuro atolls.
 Admiral Nimitz, Commander of the U. S. Pacific Fleet, chose two islands in Kwajalein Atoll, Roi-Namur Island and Kwajalein Island, as primary targets in the U. S. invasion of the Marshall Islands.
  Kwajalein Atoll contained communication and weather observation units and two Japanese airstrips on Roi-Namur and Kwajalein Islands, a seaplane base situated at Ebeye Island, a submarine base at Roi-Namur Island, and other Japanese installations scattered on various islands throughout Kwajalein atoll.
  Kwajalein atoll, particularly Roi-Namur and Kwajalein Islands, were subjected to heavy bombardment.
 This attack also sank a large number of Japanese ships in Kwajalein Lagoon.
 Bitter fighting between Japanese forces and the U. S. 4th Marine Division on Roi-Namur, and the U. S. 7th Infantry Division on Kwajalein, resulted in a U. S. victory on 4 February 1944.
 The attack of the Japanese in the Marshall Islands was the first US attack, and capture, of Japanese territory, since the land was held by Japan before the start of World War II.
 The capture of Kwajalein Atoll during Operation Flintlock provided American forces with a base of operations that assured the recapture of the Philippines and eventually the fall of Japan.
Olive Drab Cotton Field Jacket (also known as OD Cotton Field Jacket and, unofficially, Parsons Jacket, M1938 or M1941) is a field jacket used by US Army soldiers, most famously during the beginning of World War II.
 In 1941 it started to be phased in as a replacement for the wool four pocket service coat of World War I, but around 1943 it was replaced in turn by the improved M1943 model.
 Due to wide adoption, the M1941 is usually recognized as a symbol of the World War II American G.I..
 The jacket was made in a light shade of olive drab called OD number 3.
Operation "Hailstone" (known in Japan as Japanese: トラック島空襲 "Torakku-tō Kūshū", lit.
 "the airstrike on Truk Island") was a massive naval air and surface attack launched on February 16–17, 1944, during World War II by the United States Navy against the Japanese naval and air base at Truk in the Caroline Islands, a pre-war Japanese territory.
 Operation "Hailstone" is often referred to as the Japanese equivalent of the attack on Pearl Harbor.
USS "Enterprise" (CV-6), was the seventh U.S. Navy vessel to bear the name.
 Colloquially called "the Big E", she was the sixth aircraft carrier of the United States Navy.
 A "Yorktown"-class carrier, she was launched in 1936 and was one of only three American carriers commissioned before World War II to survive the war (the others being "Saratoga" and "Ranger" ).
 She participated in more major actions of the war against Japan than any other United States ship.
 These actions included the Attack on Pearl Harbor (18 dive bombers of VS-6 were over the harbor, 6 were shot down with a loss of eleven men, making her the only American Aircraft carrier with men at Pearl Harbor during the Attack and the first to receive casualties during the Pacific War), the Battle of Midway, the Battle of the Eastern Solomons, the Battle of the Santa Cruz Islands, various other air-sea engagements during the Guadalcanal Campaign, the Battle of the Philippine Sea, and the Battle of Leyte Gulf.
 "Enterprise" earned 20 battle stars, the most for any U.S. warship in World War II, and was the most decorated U.S. ship of World War II, She is also the first American ship to sink an enemy vessel during the Pacific War, the sole surviving pilot of the six planes shot down over Pearl Harbor sank Japanese submarine I-70 on 10 December 1941.
 On three occasions during the Pacific War, the Japanese announced that she had been sunk in battle, resulting in her being named "The Grey Ghost".
The Battle of Kwajalein was fought as part of the Pacific campaign of World War II.
 It took place from 31 January-3 February 1944, on Kwajalein Atoll in the Marshall Islands.
 Employing the hard-learned lessons of the battle of Tarawa, the United States launched a successful twin assault on the main islands of Kwajalein in the south and Roi-Namur in the north.
 The Japanese defenders put up stiff resistance, although outnumbered and under-prepared.
 The determined defense of Roi-Namur left only 51 survivors of an original garrison of 3,500.
Max Clifford Stormes (27 July 1903-15 November 1942) was a World War II American naval commander.
Rear Admiral Herbert James Ray (1 February 1893 – 3 December 1970) was an officer in the United States Navy who served in World War I and World War II.
 A 1914 graduate of the Naval Academy, he served on the submarines USS "H-2" and "N-3" during World War I.
 In March 1942, as Chief of Staff and Aide to the Commandant of the Sixteenth Naval District, Rear Admiral Francis W. Rockwell, he participated in General Douglas MacArthur's escape from the Philippines.
 In Australia, he served with MacArthur's General Headquarters, Southwest Pacific Area staff.
 In September 1943, he became Captain of the battleship USS "Maryland" , which he commanded in the Battle of Tarawa, Battle of Kwajalein, Battle of Saipan and the Battle of Peleliu.
 In October 1944, he participated in the Battle of Surigao Strait, in which "Maryland" joined the other battleships in engaging the Japanese battleships "Fusō" and "Yamashiro" and their escorts.
 Ray left "Maryland" in December 1944, and was appointed Deputy Director of the Naval Division of the US Control Group Council for Germany.
 After VE Day, he became the Junior United States Member of the Tripartite Naval Commission in Berlin.
 He retired from the Navy on 30 June 1949, and received a tombstone promotion to rear admiral due to his combat decorations.
The Arado Ar 231 was a lightweight floatplane, developed during World War II in Germany as a scout plane for submarines by Arado.
 The need to be stored inside the submarine necessitated compromises in design that made this single-seat seaplane of little practical use.
The Douglas SBD Dauntless was a World War II American naval scout plane and dive bomber that was manufactured by Douglas Aircraft from 1940 through 1944.
 The SBD ("Scout Bomber Douglas") was the United States Navy's main carrier-borne scout plane and dive bomber from mid-1940 through mid-1944.
 The SBD was also flown by the United States Marine Corps, both from land air bases and aircraft carriers.
 The SBD is best remembered as the bomber that delivered the fatal blows to the Japanese carriers at the Battle of Midway in June 1942.
 The type earned its nickname "Slow But Deadly" (with the SBD initials) during this period.
USS "Dennis" (DE-405) was a World War II "John C. Butler"-class destroyer escort in the service of the United States Navy.
 "Dennis" was named after Radioman Third Class Otis Lee Dennis.
 He was killed in action 1 February 1942 with Carleton Thayer Fogg (namesake of "Fogg" ) when their Douglas SBD Dauntless was lost during an attack launched by "Enterprise" on Roi-Namur, Kwajalein.
 It was one of the first offensive operations following Pearl Harbor.
