Been watching videos about the history of upper rankings in the US military, and found these interesting. In celebration the Bicentennial, in 1976 Congress posthumously promoted George Washington to General of the Armies, and declared that he would forever be senior to all other officers. The title General of the Armies has been issued sparingly in our history, given to Grant during the Civil War, to be followed by Sherman and then Sheridan in succession. The equivalent Admiral of the Navy was given to George Dewey (he remains the only man to ever achieve the rank) and later to Black Jack Pershing following WWI. Congress considered designating Douglas McArthur General of the Armies during the planning stages of the invasion of Japan, but it was dropped when Japan surrendered. The rank of General of the Army/Fleet Admiral (5-stars) was created in 1944 to give American theatre commanders seniority equivalent to other Allied commanders (most recognized a rank of Marshall that was superior to our 4-star Generals). Seven admirals and generals were promoted to 5-star during the war (Admiral Leahy, General Marshall, Admiral King, General McArthur, Admiral Nimitz, General Eisenhower and General Arnold, who headed the Army Air Corps and was later declared General of the Air Force). However, all were considered junior to General Pershing, who lived until 1949. Following the war, Admiral Halsey and General Bradley received a 5th star. The ranks of General of the Army, General of the Air Force, Admiral of the Navy and Admiral of the Coast Guard are all currently vacant. The insignia for General of the Armies has created confusion for casual observers. During the Civil War, the highest ranking generals wore 3 stars, so Grant, Sherman and Sheridan wore 4 stars on their promotions. By the time Pershing received the title, the 4-star general's rank had been made standard, and Pershing was allowed to choose his own insignia. He decided to keep to 4 stars, but wore them in gold rather than the commonly used silver. Since a General of the Armies outranks even a 5-star general, it was thought when that promotion was being considered for McArthur that he would wear 6 stars, an insignia that has never been approved. (General's/Admiral's stars are worn in a row, but for a 5-star they are arranged in a circle. It was thought the sixth star would be placed in the middle of the circle of 5). Nevertheless, there are some who now consider Washington to be our first and only 6-star general due to his 1976 promotion.
