Sorry for the problems.
On the UH-60s, are you sure they are stopped, over open terrain, and not in sprinte? Are you sure there is nothing else in the helos already (maybe taking up the space).
For the 105s, make sure they are not in sprint either. That can sometimes stop them from firing.
Beyond that, send a saved game to:

and I will check it out.
