This is a fan made film i saw posted on the arma 3 fb page its pretty damn cool and not that short took the guy nearly a year to make it gg to him enjoy!
indeed, its epic, awesome stuff, would love to get similar action in an op one day, the perfect hellstorm 
Bit too much slowmo for my taste but it was nice. I could watch a movie like this for an hour or two.
Also am i the only who felled the urge to play some CAS in arma after this?
