THose guys look pretty damn good. THe problem that I have heard about Russians that reenact is that safety checks are non-existent, and people do some really stupid stuff. Had a friend over there get shot with a BFA. Yes the BFA left one person's gun and hit another person due to gross negligence.
The cool thing is that they are pretty much the only guys that get to play on original battlefields in Europe. Germany is too scared and PC to let anyone do that. Most European countries won't let you dress in a WWII German uniform, so you really can't have a battle without two sides.
And the Russians use more original stuff in their personal kit than almost anyone else that I have seen, except for me of course.
