I guess it was just a matter of time before I caught the AFV (armoured fighting vehicle) bug. And the T-55A medium tank is as good a starting point as any, with it being a part of a series of tanks (the T-54/55) that is the most-produced in military history. They are said to be in use by up to over 50 armies worldwide which gives the tank a lot of potential in terms of colour scheme variations.
