OK, Time for a dose of reality,
The key for helo mates is to fly at night in ****e weather. The ROE alone will, prevent getting fragged. Most realistic opposition in any case have v poor ability in this situation. Can't really imagine the Iranian airforce going up against allied forces at night.
For our FJ mates, what can be done against THEIR helos at night under stict visident rules??
I wouldn't worry about that case either, the capability of most realistic adversaries at night is just too poor to worry about. (At the moment)
