The KV-1 Heavy Tank

The KV-1 is a huge monster of a vehicle weighing at 45 tonnes it was one of Russia's first heavy breed of tanks used within the second world war, it was famed for it's near impregnability. The German anti-tank weaponry of the time had nearly no way of penetrating its armour, only the lack of training and manoeuvrability allowing it to fall foul of superior German tactics.

Their size allowed KV-1s to literally crush anything beneath its giant treads, firing lines and encampments were abandoned on the sheer sight of it. The 76.2mm cannon still punched through any of the current German armour, so during 1941, it was nigh-unstoppable.

The KV-1 set the example of how a heavy tank could or should be, nearly indestructible and to cause terror in their enemy. Over the following years it did fall out of favour, but it was used as the base for the next generation of heavy tanks.
