I was gunning for Beckler at the start of the game and felt like gunning even after he went on foot. HULL got in and I got in the gunner seat, he acted odd and didn't leave the spawn, then started spamming to leave the vehicle. As far as I know, you don't get to choose your gunner, and I am a good AH gunner. HULL decided to teamkill me, so I respawned in the AH gunner hoping to get a different pilot. His friend, Zebi, got in and then immediately teamkilled me. And I know for a fact that teamkilling is against the rules.
