I hear what you all say, BUT they were supposed to be a CREW and crew look after each other don't they???
I'm sure the B17 and Lanc bomber crews wouldn't have bolted from the scene in WW2 nor would have a Huey Door Gunner in Nam.....
I think the big difference is that probably these two were not crew in the sense of a close working unit but pilot and passenger. Military crews in a war zone live together and know that at any time they can die together. In times of stress their natural instincts to run are overcome by their loyalty to each other.
As others have mentioned the pilot was possibly telling the camera man to run as the camera man was a passenger. If he had been a mate he probably still would have told him to run but the camera man (hopefully) would not have left a mate behind.
