That would be great that you could hurt your own men. Then you must control your shooting so that you dont kill allied soldiers by accident.
I've played Operation Flashpoint for some time now and I've shot the NATO medic atleast six times. There's this bug that sends medic attacking in front of the line and he's been caught in my line of fire quite often. I brought this up just because in that game you must identify the target before you can shoot and thats tricky if the distance is long. But I like that and I would love to see that same thing in MoH AA too.
If they make MoH so that you can shoot your own men, they should make some kind of script or something that enemies dont recognise you from a mile away though. That would suck, if the minute enemy sees you, you are shot at.
