World of Tanks: Jagdtiger (German Tank Destroyer)

The German Jagdtiger is a one-tank-army, with 7 Firepower and 4 Survivability so all it needs is a clear line of sight and a target!
The massive gun also gains the Big Gun rule.
Equip a Binocular Telescope to upgrade another Hit to Critical provided this tank stays Stationary, and you have an unshiftable tank destroying machine!
