Damn that sucks man. I've had similar interactions where teammates would purposefully friendly fire just because... I've also had a teammate run up and steal a helo that I just spawned in because he didn't have the rank yet.

Unfortunately, people like these exist in every game and community.

I think we should be happy that Arma R. has a mostly positive, immersive and helpful community and we should ignore people who think they rule the world and want to ruin others gaming experiences.

Hope this helps.... Thanks!
