Wirth was a member of Travers' platoon in the 82nd Airborne Division. He is first seen in Infinite Mischief giving Dane a message from Sgt. Setzer requesting support. Travers and him went to help Setzer themselves after Dane held the Town Hall. Setzer then ordered Wirth to report to the colonel and tell them about the situation and status of Harding and his spotter.
