A flying ace or fighter ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat.[1] Batz flew 445 combat missions and claimed 237 enemy aircraft shot down. 234 of these victories were achieved over the Eastern Front, including at least 46 Il-2 Sturmoviks, but he did claim three victories, including one four-engine bomber against the United States Army Air Forces (USAAF) over the Ploieşti oil fields. Batz was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves and Swords.
