Learn the historical facts. French and Brits had a superior Army in the north too...which was much better equipped and stronger overall.
Problem was they had 1.ww tactics, poor moral, slow and long command-ways, was surprised every time and get into german "Kesselschlachten" with good plane support.
but allies had much better tanks and weapons.
germans had their commander at the front in the first tanks, had fast and light tanks, overrun the front and cuts the enemy off behind their line and close the pockets.
axis tanks had mostly no chance to penetrate french tanks....so they shot them immobile and let them stay there to let work paks
Where did I said germans were equipped better or had better tanks?
