The German Panther Tank was meant to replace the Panzer III and the Panzer IV, although all served till the end of WWII. The Panther was also meant as a direct counter to the SovietT-34 which outclassed both the Panzer III and Panzer IV. Officially designated Panzerkampfwagen V (PzKpfw V or Panzer V) or Sd kfz. 171, the Panther was equiped with a powerful long 75 mm main gun and two MG 34's or MG 42's. The Panther gun is purposely design as an anti-tank weapon, it has a long barrel gun and uses more powerful ammunition, thus the muzzle velocity is significantly increased, the gun is deadly to most allied tanks even at the range of 2000 meters. The Panther was also the first German tank to encorperate 80mm sloped armor (or any type of sloped armor), first seen in the T-34, which more effectively deflected enemy anti-tank rounds, the armor has the equvilent protection of 100mm of regular armor, which most allied main battle tank cannot punch through. Though it has a thinner 50mm side and rear armor and the 30mm armor found bottom of the thick frontal armor, which is possible to punch though using M61 75mm armor piercing round used by M4 Sherman at close range. Despite it has many downsides and easy to brake down due to its complicated design, the Panther was one of the best tank during the WWII, due to its heavy firepower and superior frontal protection.
