Single firing his Bulldog and almost instakilling. Me and 2 other players rush him around a corner... before we can put 1 bullet into him he semi-auto killed all of us in 5-6 shots. he was 6-7 feet away from us, this was super CQB. My squad wasn't anything amazing but we were at the top of the scoreboard on our team.
