m18 hellcat
The M18 Gun Motor Carriage, also known as Hellcat, was a World War II American tank destroyer armed with a 76 mm cannon. The vehicle was well-known for its open top turret and very light armor, but also for its extremely high speed and firepower which increased its survivability in actual combat.
It is considered the fastest tank of the entire war, with a top speed of up to 89 km/h on road.
