'there was no 3-man SAM crew'
That may well be true but you really are missing the point. You can only say that with hindsight.
At the time, while hovering in the day/dark (it doesn't matter which - you can't watch every patch of scrub within a mile, through 360 degrees, for threats), you have no idea whether someone is lining you up in his sights.
Without knowing the context, but from what I can see, this crew prosecuted a professional attack and were undoubtedly at risk in doing so. All this talk about 'wounded men crawling away' is total nonsense. You cannot tell that for certain , especially when you have about 1.2 seconds to decide, while you are trying to do about a dozen other things at once (including fly) and you could be on the recieving end at any minute.
I think that those that have been there are, very patiently, trying to explain this to you. Now you can continue to be ignorant or you can listen to them. It is NOT the same as a gameboy.
Hope that helps.
