Unfortunately for Poland, it's abundant "horse power" was not enough to stop the German invasion in 1939.
The 7TP tank was one step ahead of the Pz I and Pz II in terms of firepower and armor, but they were just too scarce to make a difference and were defenseless against the Luftwaffe.
The PZL P.11 fighter was not even a match, in terms of speed, to face most German bombers.
What more could they have done against the Bf 109's and Bf 110's ?
