Alright I didn't thought that people would take this matter this serious.
I've played this game since release and comparing this event with all the bullshit other people did to gain an advantage over others is just laughable in my opinion.
Just to make it absolutly clear: I did not go into the battle hoping to kill "friendlies", my intention was to gain as much damage for the patrol mission as possible.
I also recorded and uploaded the video because I didn't think I was doing something wrong, if that would have been the case I wouldn't even have replied to this thread and never would've uploaded the video.
All this could have been avoided if it would be possible to have multi nation battles, but I guess we will never see that. I hope you will understand my thought process now.
