According to the U.S. Navy SEAL official site, SEAL teams 1,3,5,7, and 17 are based at Coronado, CA and teams 2,4,8 and 10 are based at Little Creek, VA. The official site does not mention team six’s home base which is Naval Air Station Oceana, Virginia.
 
SEAL Team 6 (ST6) is the top tier counter-terrorism Unit (CTU) and Special Mission Unit (SMU) and is no longer actually called Team Six. Today, the same outfit is known by its designation NSWDG, Naval Special Warfare Development Group or “DEVGRU”. Not much more is known about DevGru as this excerpt from the Seal Team Six facebook page explains:  "REMEMBER Team6, but there is NO team6, you are under don't need to know basis"...!!!,
 
The vast majority of information surrounding DEVGRU is highly classified and details of its activities are not commented on by either the White House or the Department of Defense.

Recently, the White House released that DevGru had carried out the operation to kill and positively identify Osama Bin Laden. This is an unusual event: 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.
 
The Team was labeled 6 at the time to confuse Soviet intelligence about the number of SEAL teams in operation at the time. There were only two others. Team 6 poached the top operatives from other SEAL units and trained them even more intensely from there. Even among proven SEALs the attrition rate for Team 6 is reported to be nearly half.
 
There are no names available for current Team 6 members, but the CIA does recruit heavily from their numbers for their Special Operations Group, so it makes sense that they were chosen to work with the CIA on this mission. Team 6 is normally devoted to missions with maritime authority: ship rescues, oil rigs, naval bases or land bases accessible by water. There are no waterways near Bin Laden's compound.
 
When a former Navy SEAL was called for a comment about “TEAM6” all he could say was:"You know I'd love to help you man, but I can't say a word about Team6. "There is no Team6."
