Comparing: Jagdtiger vs. Tortoise

Developed from 1942 through 1944, the heavy tank destroyer, with the chassis of the Tiger II heavy tank, became the heaviest mass-produced armored vehicle ever. According to various sources, 70–79 tank destroyers were manufactured from 1944 through 1945. The vehicles saw service in the 653rd and 512th Heavy Panzerjäger Battalions.

The development of this assault tank began in Great Britain in 1942. The design was finalized by February 1944, and an order was placed for 25 vehicles. However, by the fall of 1947 only five tanks had been manufactured.
