Tiger I
The Tiger I has been called an outstanding design for its time. It has also been called overengineered. It was built using costly materials. The methods used to make it were  labour-intensive. Early version of the Tiger would often have track failures and breakdowns. It also had a limited range because it used a large amount of fuel. The tank was costly to maintain but was mechanically reliable. It was hard to transport. It could not move well in areas with mud, ice and snow. These conditions would often jamming the tracks solid.
