That's a link to the guy in the vid/pic original thread. He is rank 75 Valor, which means he is in most if not all BM gear. The people he is up against are underpowered compared to him.
Note: in the pic posted the entire team has lots of kills and damage dealt, but the game was a tie, (neither side even got past the first doors) they obviously weren't interested in winning, only in killing and putting up "big numbers".
