I Armored Corps (United States)

The I Armored Corps was a corps-sized formation of the United States Army that was active in World War II.

The Corps made landfall in Morocco in French North Africa during Operation Torch in November 1942, the Allied invasion of French North Africa, as the Western Task Force, under the command of Major General George S. Patton, the first all-American force to enter the war against the Germans.

Following the successful defeat of the Axis powers under ''Generalfeldmarschall'' Erwin Rommel in North Africa, in May 1943, I Armored Corps was redesignated as the Seventh Army on 10 July 1943 while at sea en route to the Allied invasion of Sicily as the spearhead of Operation Husky.
