During his time in the army, he befriends Private Ronald Daniels during basic training. He also can somewhat speak German, thanks to his German-Jewish heritage.
He fights along side with Ronald "Red" Daniels throughout the campaign. In Collateral Damage, his platoon learns that he is German and that he can speak German. He is later captured in Ambush by German soldiers and Daniels tries to save him, but fails to save him. He is sent to a P.O.W camp and then sent to Jewish P.O.W Labor camp runned by Metz. In the Epilogue, he is rescued by his 1st Infantry Division platoon from being executed by Metz. He is seen badly beaten and malnourished. He is later seen recovering in a U.S. Army hospital and thanks Daniels for saving his life.
