Somehow, while I was doing multiplayer, I managed to hit myself with an AA-12. I had missile inbound warnings before I fired, so I just assumed it was an AMRAAM, but the chat log said it was an R-77, and it said I killed myself. I did fire one, so it's not completely impossible, but how could it have happened? Did I run into it? I'm sorry, I don't have the track, otherwise I'd have watched it to see what happened.
