Its a mess.
Seriously, arma is a mess.
The AI is highly retarded. When I order a chopper to land it insist to land at a particular location - in the trees, resulting a crash. When I contruct simple waypoints the helicopters simply crash into mountains and all that crap. I placed 6 satches charges on my unit. When export it to single mission there is only one.
There is a lot of stuff that simply puts me off the chair while playing this game. Its not that enjoyable anymore. Its a mess. A helicopter shouldnt need a script in order to avoid crashing, and my satchescharges shouldnt magically dissapear either.
