Russian Mi24P - Gscholz and I had a thread going a couple years back about just how rare it was for the Mi24 to get shot down, so few if any vids back then of it actually going down, even after taking manpads hits - I think there were 3 or 4 videos in that thread of the Mi24 surviving manpads and making it out of the video at least.
This one - I can't tell if the first flashes are the Mi24 launching its own weapons, then taking a hit to the tail, or if all the flashes are from incoming rounds hitting, and the last one was just the largest warhead/flash, or what. Also don't see a missile trail at all, could be AAA, and I don't read Russian or Dirkstanian in the comments to see what's being said. As per the previous thread mentioned, it was agreed by all that the Mi24 is one tough bird, and even looking closely at this video, the tail was still intact pretty much, looks like just the tail rotor got chopped, not much else.
