“The news today is riddled with references to the Navy’s elite “SEAL Team 6,” the team being hailed for killing Osama bin Laden. But what exactly is SEAL Team 6? For most people it’s the stuff of Tom Clancy and Brad Thor novels. But in the spy and military world, it is an elite black ops fighting group shrouded in secrets that reports to the president himself.

“Officially, the team’s name is classified and not available to the public,” Business Insider writer Robert W. Johnson reports, “technically there is no team 6. A Tier-One counter-terrorism force similar to the Army’s elusive Delta group, Team 6′s mission rarely make it to paper much less the newspaper.”

He continues:

The members of Team 6 are all “black” operatives. They exist outside military protocol, engage in operations that are at the highest level of classification and often outside the boundaries of international law. To maintain plausible deniability in case they are caught, records of black operations are rarely, if ever, kept.

The development of SEAL Team 6 was in direct response to the 1980 attempt to rescue the American hostages held in Iran. The mission was a terrific failure that fell apart at many points and illustrated the need for a dedicated counter-terrorist team capable of operating with the utmost secrecy.

Johnson explains the name is allegedly an intentional lie that dates back to the time of the Cold War. At the time, there were only two other SEAL teams and the name was meant to confuse the Soviets.”
