Joint Special Operations Command
The United States Naval Special Warfare Development Group (NSWDG), commonly known as DEVGRU or SEAL Team Six, is the U.S. Navy component of the Joint Special Operations Command. It is often referred to within JSOC as Task Force Blue. DEVGRU is administratively supported by Naval Special Warfare Command and operationally commanded by the Joint Special Operations Command. Most information concerning DEVGRU is classified, and details of its activities are not usually commented on by either the Department of Defense or the White House. Despite the official name changes, "SEAL Team Six" remains the unit's widely recognized moniker. It is sometimes referred to in the U.S. media as a Special Mission Unit.

DEVGRU and its Army counterpart Delta Force are the United States military's primary counter-terrorism units. Although DEVGRU was created as a maritime counter-terrorism unit targeting high-value targets, it has become a multi-functional special operations unit with several roles that include hostage rescue, special reconnaissance, personal security, and other specialized missions.
