I have a friend who will love this.  Plays a Russian Army in Flames of War and likes to wear theme t shirts.  Cool, cheap, and simple.  

Prior to WWII, Stalin purged over 50% of the Red Army officers in fear of a military coup.  The Soviet Army's lack of leadership is cited as a major contributor to their inability to even slow down the Germans when they invaded in 1941.  

The Russian Army featured one of my favorite historical vehicles, the T-34 tank.  It has been credited with being the best tank of WWII.  I got to see one a few years ago at a tank museum.   Very cool.
