"For when you absolutely must have the biggest tank on the battlefield. With much greater armor and firepower, it easily dispatches smaller tanks while absorbing tremendous punishment.

The Heavy Tank Mk.2 (level 2 Heavy Tank) is a standard heavy tank unit. It can be upgraded to the Heavy Tank Mk.3.
Armored tactics evolved at a rapid pace throughout WWI, in response to the attrition of trench warface. The first tanks were slow, underpowered and prone to mechanical breakdowns, but by the end of the war, Allied superiority in Heavy Tanks such as British Mark V played a decisive role in key battles such as Cambrai and Amiens.
