Insignia of the 90th Infantry Division. Called the "Tough Ombres," the 90th Infantry Division was raised from draftees from the states of Texas and Oklahoma during World War I. The divisional insignia incorporates the letters "T" and "O" to symbolize both states. These letters later yielded the nickname "Tough Ombres," symbolizing the esprit de corps of the unit. The 90th was also sometimes called the "Alamo" division during World War II.
