The Polish Army in WW2 was horribly equipped(Relied on outdated weapons and equipment), had incompetent Generals and their tactics were horrible(Charging German steel with horses is one example); they're a prime candidate to be put into a German or US doctrine.
Like really, are you actually arguing that the Polish were instrumental in Germany's defeat in WW2, and not the British Empire? If what you say is true, then Poland, and no the UK would be on the UN Permanent Security Council.
Britih tend to forget about polish divisions saving Gr. Brt. in the air or contribution in breaking Enigma.
Horribly equipped and others arguments are made by bad PR for year (like charging tanks with horses). Poland allocated around 40% of the budget into military.
In 1935 Poland army could destroy III Reich that why we were looking for a good excuse to attack German but we were unable to provoke them despite attempts.
We made proposition for France to attack Reich together but France did not agree.
About bad equipped... Polish AT carabine, UR35 was a way better carabine than Panzerbuchse.
Or for example 7TP tank. It had little worse armor than PzI and II but the cannon was superior.
Problem was that polish superior units/equipment was stretched while Nazi where
concentrated.
So please, learn something and don't let propaganda to take you.
Poland were fighting for a month with the two biggest armies in the world.
France fell after 2 weeks only with Nazi despite France had a way better equipment so what does it tell about their generals?
Keep in mind that Poland was planning big military revolution in 39'-42'. If Germans stayed for 40/41 they would recived much more difficult time cause of new planes and other stuffs.
The only true thing is the thing about Generals and Commanders. After death of Piłsudski, there was no one to coordinate all of this.
End of off top.
Sorry
Major byt I could not leave non-historical things.
