I don't have a problem.
The German Fourth Luftflotte, was responsible for this area, while its Soviet counterparts were primarily the
Fourth and Fifth Air Armies, along with three air corps from STAVKA reserves. Both air forces were roughly
equal in size at about 1000 combat aircraft each. The Luftwaffe fighter units were mainly equipped with
Bf 109G-2/-4's and Fw 190 A's, while the VVS possessed a mixture of the latest Yakovlev and Lavochkin fighters,
along with large numbers of IL-2 Sturmoviks and Pe-2 bombers. In addition, there was a steady flow of lend-lease
aircraft: P-39's, A-20's, P-40's and Spitfire V's.
