I am currently playing around with quickly(HA) painting up a US Armored Company for Flames of War. I still have yet to fully finish painting an army of mine over 1000 points. This is just a little test work in progress on one of my Stuarts from the list I came up with. I have taken more of a sharper highlight approach which I don't normally do on 15mm. And then tried to dirty the tanks up a bit. I dunno, just pristine armor doesn't do it for me. I like the look of some mileage on the boys.
Now if only I could find a 15mm Telly Savalas chewing on a stogie... I would be a happy man!
