Having played a lot of OFP, Arma, Arma II, OA, PMC, etc that wasn't impressive. The helo had been scripted to sit there. Even helos in Arma II on a Hold waypoint will move if shot or even shot at. Anyone that has some experience with the series, particularly if you understand the editor and AI reactions won't be hailing this video as anything but shooting ducks on a pond.
