I'm not sure where you deriving that fear from especially after the initial fire from the helicopter. All I was hearing was the gunner being excited he got to shoot something.

I realize Americans grow up late but there's also a big difference between being in your (mid?) twenties and being a kid, let alone a young one. How old do you need to be before you are responsible for your own actions and mistakes? I would hope it's before they put you in a helicopter armed to the teeth.

Theres plenty of blame to go around but some of it surely lies on the people lighting up a van recovering wounded people which was of no apparent treat. You can even hear him get stressed as the body they are carrying is getting closer to being loaded into the van, because hes about to miss his opportunity to shoot.
