The Berlin Victory Parade was a chance for the Allies to come together and celebrate the end of World War 2, but as it played out, it would lead to the West becoming increasingly paranoid towards the Soviets.

The revelation of the new Soviet IS3 heavy tank was a cause for concern amongst the West with it being more powerful than anything they had to show. And if this is what they had in 1946, what would they have in the near future?

Different Western nations then looked for ways to defeat such heavily armoured tanks, and it was the British that would develop a gun so powerful that the vehicle it was mounted to literally shook itself apart when firing.

In this Tank Chat Reloaded, Paul Famojuro (FamTheTankMan) has a detailed look at the L4 183mm gun developed to counter the potential future threat of Soviet heavy armour, as well as the proposed vehicles which would mount the biggest tank gun in history.
