Definitely Non Standard
The "pie plate" over the tail rotor hub, gear box cover shape, pointed aft end, horizontal stabilizer sweep (forward or has it just rotated around the pivot point?), and the silvery paint suggest stealth treatment. The fin appears to be shorter as well. It looks to me that he came in a bit short and hit the tail boom on the wall. With hover antitorque thrust coming in, the tail boom would have been under a lot of stress and broken off with too much encouragement. Note that the bit outside the wall is to the left of the forward part of the tail boom and rolled upside down, which is where the tail rotor thrust would take it.
