Today I was playing on Arma 3 Alpha Development Build and I was on the Mission Editor and basically what I done is I put 2 groups of Blufor and Opfor facing each other about 100 meters away from eachother.
I then placed 5 Blufor hunters as obistacles so the Blufor team can get behind them and use them as cover, I also applied that for the Opfor, but using EMPTY blufor hunters.
I have tested this four times and the same has applied for each time. Please look in to this as it disallows people to make Missions for example, destroy the captured Blufor vehicle.
It would be devastating to do a mission like that and you blow it up and then get show by your friends.
Here you are anyway, hope you can look in to this.
