US Army 90th Infantry Division shoulder sleeve patch with a red T and O monogram on a black field

Shoulder sleeve insignia of the United States Army 90th Infantry Division, nicknamed the Tough Ombre Division. The division’s insignia with the letters T and O, representing the states of Texas and Oklahoma where the first troops were drafted, is the source of the unit's nickname. The 90th landed on Utah Beach behind the initial assault on D Day, June 6, 1944. The division then advanced into the Saar Region of Germany in early December 1944. On January 5, 1945, the unit was redeployed to Belgium for the Battle of the Bulge. In late April, the 90th advanced to the German/Czech border, where they liberated Flossenbürg concentration camp on April 23, 1945. Troops discovered about 1,500 survivors at the camp and some 6,000 survivors near the camp, who had been forced to evacuate Flossenbürg in death marches. The unit was en route to Prague when Germany surrendered on May 7, 1945. The 90th conducted patrols along the border until their return home on December 16, 1945. The Division was inactivated on December 27, 1945.
