“A Government Accountability Office report published earlier this month contains a fascinating and hitherto secret detail: the exact size of the Navy’s SEAL Team 6. Operating since the late 1980s under the cover name Naval Special Warfare Development Group, Team 6 is a special mission unit that works for Joint Special Operations Command. JSOC performs some of the most secret and sensitive missions for the United States, including the May 2011 raid on Osama bin Laden’s compound in Abbottabad, Pakistan (a mission for which Team 6 provided the ground force). As such, the military has always closely guarded details on how many personnel the unit has.”
