Major General Fred Livingood Walker (June 11, 1887 – October 6, 1969) was a highly decorated senior United States Army officer who served in both World War I and World War II and was awarded with the second highest military decorations in both wars, the Distinguished Service Cross.
 During World War I he commanded a battalion on the Western Front, fighting with distinction in the Second Battle of the Marne in July 1918.
 During World War II, Walker commanded the 36th (Texas) Infantry Division throughout its service in the Italian Campaign, from September 1943 until June 1944.
The Battle of Okinawa (Japanese: 沖縄戦 , Hepburn: Okinawa-sen ) (Okinawan: 沖縄戦 , "Uchinaa ikusa " ), codenamed Operation Iceberg, was a major battle of the Pacific War fought on the island of Okinawa by United States Marine and Army forces against the Imperial Japanese Army and included the largest amphibious assault in the Pacific War during World War II, the April 1, 1945, invasion of Okinawa itself.
 The 82-day battle lasted from April 1 until June 22, 1945.
 After a long campaign of island hopping, the Allies were planning to use Okinawa, a large island only 340 mi away from mainland Japan, as a base for air operations for the planned invasion of the Japanese home islands.
Robert Lee Sherrod (February 8, 1909 – February 13, 1994) was an American journalist, editor and author.
 He was a war correspondent for "Time" and "Life" magazines, covering combat from World War II to the Vietnam War.
 During World War II, embedded with the United States Marine Corps, he covered the battles at Attu (with the U.S. Army), Tarawa, Saipan, Iwo Jima, and Okinawa.
 He also authored five books on World War II, including "Tarawa: The Story of a Battle" (1944) and the definitive "History of Marine Corps Aviation in World War II" (1952).
 He was an editor of "Time" during World War II and later editor of "The Saturday Evening Post", then vice-president of Curtis Publishing Company.
Battle of Albert (21–23 August 1918) was the third battle by that name fought during World War I, following the First Battle of Albert and the Second Battle of Albert, with each of the series of three being fought roughly two years apart.
 This smaller third battle was significant in that it was the opening push that would lead to the Second Battle of the Somme and involved the Australian Corps.
 This attack opened the advance, with the main attack being launched by the Third Army along with support from the Fourth Army.
 The Second Battle of Bapaume, from 25 August to 3 September, was a continuation of this battle.
The Second Battle of the Marne (French: "Seconde Bataille de la Marne" ), or "Battle of Reims" (15 July – 6 August 1918) was the last major German offensive on the Western Front during the First World War.
 The attack failed when an Allied counterattack by French and American forces, including several hundred tanks, overwhelmed the Germans on their right flank, inflicting severe casualties.
 The German defeat marked the start of the relentless Allied advance which culminated in the Armistice with Germany about 100 days later.
The 93rd Infantry Division was a "colored" segregated unit of the United States Army in World War I and World War II.
 During tough combat in France, it soon acquired from the French the nickname "Blue Helmets".
 This referred to the service of several of its units with the French Army during the Second Battle of the Marne.
 Consequently, its shoulder patch became a blue French Adrian helmet, to commemorate its service with the French Army during the Spring Offensive.
George Johnson McMillin (November 25, 1889 – August 29, 1983 ) was a United States Navy Rear Admiral who served as the 38th and final Naval Governor of Guam.
 He graduated from the United States Naval Academy in 1911 and served as an officer during four separate conflicts: World War I, the occupation of the Dominican Republic, the United States occupation of Veracruz, and World War II.
 He served on the staff of both the Naval Academy and the Naval War College as well.
 He is most remembered as the commander who surrendered Guamanian forces to a much larger Japanese force during the First Battle of Guam, only the second battle of World War II involving the United States.
 He had previously evacuated all but one civilian American citizen from the island and attempted to rebuild defenses after a strong typhoon devastated the island the year before.
 On December 8, 1941, Japanese forces invaded Guam and McMillin surrendered two days later.
 He spent the rest of the war at various Japanese prisoner of war camps.
Henri Mathias Berthelot (1861–1931) was a French general during World War I.
 He held an important staff position under Joseph Joffre, the French commander-in-chief, at the First Battle of the Marne, before later commanding a corps in the front line.
 In 1917 he helped to rebuild the Romanian Army following her disastrous defeat the previous autumn, then in summer 1918 he commanded French Fifth Army at the Second Battle of the Marne, with some British and Italian troops under his command.
 In the final days of the war he again returned to Romania, and then briefly commanded French intervention forces in southern Russia in the Russian Civil War.

 He was heavily decorated for valor, and is one of the iconic fighting men of the American Expeditionary Force during World War I.
 He is most famous for commanding the 38th Infantry Regiment during the Second Battle of the Marne, and earning himself and the regiment the moniker, "Rock of the Marne" (later adopted by the entire 3rd Infantry Division).
