Conqueror Gun Carriage
The Conqueror Gun Carriage is the granddaddy of British SPG tanks, and arguably the granddaddy of many other SPGs in World of Tanks as well. As a Tier 10 British SPG, it is the last of its line and rightly so. With outrageously high alpha damage and incredible amounts of frontal armor, the Conqueror Gun Carriage is one of the only SPGs in World of Tanks capable of shrugging off an impressive amount of damage.
Not only that, but the Conqueror GC has a high shell arc, making it easier to hit enemies in locations that would otherwise be impervious to SPG attacks. The only letdown with this Tier 10 SPG is its accuracy and poor gun range. But with damage like this, who cares?
