Diorama: "What If" East Germany vs West Germany War

One tip I can use is get WHITE primer.  Use the primer for the color of the building and for priming the other kits, two birds with one stone. 

I also love the idea, im working on a 'What If' myself right now.

Here is a typcal West German Village during REFORGER 84 Operation Certain Fury

I love the concept. I suggest you try googling some images of Germany to get an idea of the building colors. Prior to the adoption of the TRI color NATO camo in the second half of the 80s, Bundeswehr AFVs were in a dark olive color, that really does not match any buildings in Germany. Especially in the towns and villages. Most of those are brick, stone, or wood and not gonna be in a similar tone.
