The 20mm antiaircraft guns of the SS panzer regiment 12 shot down 23 allied aircraft during 10-3 august 1944.
German 12th SS panzer division lost very few tanks to fighter bombers during that time, they damaged some to be repaired though. They lost a number of trucks though.
Artillery damaged quite a few tanks, most could be repaired. The terrain made tanks very hard to spot from the aircraft.
