Sorry for the late posting, but I had to say, if you do that work with a regular brush, you shall be a terror with an airbrush! I begin to tremble at the results, once you've hit stride!

LOL! A pair of poor T-28s against a mech armed with twin 7.5 cm KwK 42 L/70?? Yikes for the Soviets!
I believe it's the hundreds 'just over the hill' that will make the difference.

And, given the abilities of Soviet attack coordination at the time, two at a time should model it well enough.
