P 47 Thunderbolt vs Tiger tank

While the AP projectiles from the .50 in machine guns could not penetrate the front, side, or turret armor of enemy tanks, they sometimes penetrated the engine grilles and exhaust system of the German Pzkpf Mk IV or Pzkpf V (Panther), disabling the vehicle.[37][39][40] The .50 in guns were ineffective against heavy German tanks, such as the Tiger I, and the 500 lb bombs, 4.5 in (115 mm) or 5 in (127 mm) rockets were very imprecise.
