I just watched this video from Red Wrench Films and thought it would be cool to add a couple more vickers tanks into the British line. Many of them are variants of the Mk.3 such as the 3i and the 3M which had ERA on it. The mk.4 was a fail, but it did exist, and the turret went on to be used by the mk.7 which is already in the game. The turret was also given to Brazil shortly after the mk.4 was scrapped, and it became the eet1 osorio which would be cool to see.
