There is no SEAL Team 6. T6 was created by Richard Marcinko and he was assisted by an acquaintance of mine, Michael Thornton USN SEAL MoH. They created T6 in 1980, in 1987 T6 ceased to be and it became DEVGRU (Naval Warfare Development Group). DEVGRU has a completely different mission profile than the SEALs. The only thing the SEAL Teams and DEVGRU have in common is that they all go through BUDS.
