Team Flie - The Headhunters.

Every fireteam has their squadleader; and their squadleaders are, more often than not, the strongest and most dangerous member of them. So what exactly happens when you put the leader of each fireteam into one, incredibly dangerous group? You get the Headhunters, a quartet of 4 hyper-lethal Spartan leaders; led by the most lethal and dangerous one of the four: Master Chief John-117.
