I have found almost nothing whatsoever about this location on the internet.
Only a scientific evaluation about the developing flora in the area.
We were looking for a couple of entirely different locations - East german and Soviet bunkers in the same area - but we didn't have any exact locations for those, only some rudimentary ideas that I got from scanning Google Earth.
One of those ideas turned out to be the shooting range of the local gun club...found that out after walking a mile through the woods...
The next try however turned out to be a little gem.
We found this former soviet training area just walking through the woods. We only found the warning signs as we left - always be careful in these places, there's usually still some old ammunition contaminating the area!
Here are the first couple of photos.
