I saw an ad for OFP:R at www.wargamer.com. It showed the rear of a double-rotor helicopter. It wasn't a KA-25/-27-or -29. Must have been a KA-50.
The ad is randomly generated - got to wargamer.com and refresh until you see it on the left side of the home page.
This'll be interesting to explain... a KA-50 in 1983?
