Reaching an Actual Army Theme!

So today after much thinking and receiving my pig iron heads in, my army is bent for a destructive path! I'm going to write the fluff for it later on, give me a couple of weeks to do some WWII research and I'll have it all written up.
Here is what I have so far...

Name: Shadow Corps
Tactics: Blitzkrieg, Gun-lines, and Mobilization.
