Was enemy mine fields that caused most of the problems at kursk, but point taken.
Describing the defences that presented themselves to the German Offensive at Kursk-
"Zhukov first packed the salient with 2 entire Red Army Fronts (Armies), then he constructed field defences. By late June, these crisscrossed the whole salient.Each system had a triple trench line with babred wire and mines front to rear. Countless mines were laid along the perimeter- seven for every 2m (7ft) of front."
But Point taken...ILs had huge impact in the Battle of Kursk, but it also states that "Two-thirds of German tanks destroyed in the battle were the victims of mines. Others fell prey to the Red Army's superb 76.2mm (3in) anti-tank gun."
Guess what Im sayin is that id like to see the Yak-3 before any other model Yak
