As well as that moment when he first sees the Giant, the first thing he does after his Oh Crap moment is quickly try to get Hogarth away from what he believes to be a threat.
General Rogard's Kick the Son of a Bitch with Mansley. After the latter orders the nuclear missile fired at the giant, Rogard points out that they don't have enough time to get out of the blast zone. Mansley says Screw This, I'm Outta Here!, but Rogard orders his men to "make sure he stays here like a good soldier," and keep from running. Rogard then prepares to Face Death with Dignity. Of course the missile doesn't kill any of them, but seeing Mansley get get what's coming to him was very rewarding.
