This reminded me of a Russian Colonial Marine that I saw yeeeeeeeeeeeaaaaaaars ago on another forum I used to frequent. I was able to find pictures of it and I think the UPP would have been more unique had they looked somewhat like this. It's hard to see but the figure has a "slightly futuristic" styled AK (somewhat tac'd out and with a drum mag by the looks of it). I'm not sure if the creator was inspired by the UPP idea or not.
The conversation in that old thread was pretty similar to what some of us have said in this one about what their equipment would look like, a Hind inspired drop ship was specifically mentioned.
