Summary of career

Aerial victory claims

According to Obermaier, Koall was credited with at least 38 aerial victories claimed in an unknown number of combat missions. With the exception of two claims over Yugoslavia, all of his aerial victories were claimed on the Eastern Front. Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found documentation for 37 aerial victory claims. This number includes 35 claims on the Eastern Front and two over the Western Allies in Yugoslavia.
Victory claims were logged to a map-reference, for example "PQ 1011". The Luftwaffe grid map covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of about. These sectors were then subdivided into 36 smaller units to give a location area in size.
