“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. However it has a very high population cost and the slow rate of fire can cause it to be bogged down by overwhelming odds.”
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.
