Well that was easy(ish). I started off painting my Bolt Action force with my little (but mighty?) Mk VI B. I finished it out in an evening and am rather pleased with it. I opted for the caked on dust wash much like my Incandescent Coyotes. Google any image of a combat vehicle in a desert environ and they all invariably are caked with dust.
The British, Dazzle camo style that was used in the desert campaign seems simple but is rather difficult to achieve. Painting straight, diagonal lines across the hull of a tank hasn't gotten any easier despite having painted a multitude of 40k tanks over the years.
This particular color scheme isn't based on any sort of historical unit, rather it just looked the part to me going off of the myriad examples that can be found online. The markings placement is also based off of what I found in google searches, though truth be told there seems to be little rhyme or reason to any of it.
Also I figure it would difficult to take a whole lot of pride (or any for that matter) in crewing such a cramped, uncomfortable and ridiculously inadequate combat vehicle. Apparently the tank's crew agrees as they've named it 'TOAD'.
