Top Ten Tanks

No. 6: Mk IV Panzer (Ger)

First produced in 1937. Top speed: 24.8 mph. Range: 130 miles. The Maybach V-12 gasoline engine gives a power-to-weight ratio of 10.6 horsepower per ton. Armor thickness: 50 millimeters. Primary armament: 75-mm gun.

The Mk IV scores an average ranking for mobility, and gets good points for armor and firepower. But the Mk IV Panzer really disappoints in the ease-of-manufacture category. The Mk IV is a complex, heavily engineered machine, and like all German tanks, it was not easy to mass-produce. Its fear factor score is very high: in the early days of World War II this tank was unstoppable.
