What infantry groups were assigned to Omaha?

Omaha Beach during the D-Day invasion of June 6, 1944, was primarily assaulted by the 1st and 29th Infantry Divisions of the United States Army. The 1st Infantry Division, known as the "Big Red One," and the 29th Infantry Division, which included units like the 116th Infantry Regiment, faced heavy resistance from German forces. These units were tasked with securing the beachhead and advancing inland despite facing significant challenges, including fortified defenses and difficult terrain.
