Last Iron Banner, had the bounty to get three kills with a heavy weapon. Could not get the third to save my life, using a rocket launcher, no tracking. Finally, saw my chance. Opponent running blindly in front of me. Still, I had to make sure, so I bounded into the air and came up behind him and at close range fired... My rocket launcher had a pretty good sized blast radius, it turns out. But I got that bounty done. I like to think it counted me killing myself rather than the other guy.
