Roles and Responsibilities
When SEAL Team Six was first created it was devoted exclusively to counter-terrorism with a worldwide maritime responsibility; its objectives typically included targets such as ships, oil rigs, naval bases, coastal embassies, and other civilian or military bases that were accessible from the sea or inland waterways.
On certain operations small teams from SEAL Team Six were tasked with covertly infiltrating international hot spots in order to carry out reconnaissance or security assessments of U.S. military facilities and embassies; and to give advice on improvements in order to prevent casualties in an event of a terrorist attack.
Although the unit was created as a maritime counter-terrorism unit, it has become a multi-functional special operations unit with multiple roles that include high-risk personnel/hostage extractions. Such operations include the successful rescue of Jessica Buchanan and Poul Hagen Thisted, the attempted rescue of Linda Norgrove, the successful rescue of American doctor Dilip Joseph and in 1991 the successful recovery of Haitian President Jean-Bertrand Aristide and his family during a coup that deposed him.
After SEAL Team Six was disbanded and renamed, the official mission of the currently operating Naval Special Warfare Development Group is to test, evaluate, and develop technology and maritime, ground, and airborne tactics applicable to Naval Special Warfare forces such as Navy SEALs; however, it is presumed this is only a small part of the group's work assignment and more of a cover.
DEVGRU's full mission is classified but is thought to include pre-emptive, pro-active counter-terrorist operations, counter-proliferation (efforts to prevent the spread of both conventional weapons and weapons of mass destruction), as well as the elimination or recovery of high-value targets (HVTs) from unfriendly nations. DEVGRU is one of only a handful of U.S. Special Mission Units authorized to use pre-emptive actions against terrorists and their facilities.
DEVGRU and the Army's Delta Force train and deploy together on counter-terrorist missions usually as part of a joint special operations task force (JSOTF).

Famous quotes containing the words roles and and/or roles:
“A concern with parenting...must direct attention beyond behavior. This is because parenting is not simply a set of behaviors, but participation in an interpersonal, diffuse, affective relationship. Parenting is an eminently psychological role in a way that many other roles and activities are not.”
—Nancy Chodorow (20th century)
“Productive collaborations between family and school, therefore, will demand that parents and teachers recognize the critical importance of each other’s participation in the life of the child. This mutuality of knowledge, understanding, and empathy comes not only with a recognition of the child as the central purpose for the collaboration but also with a recognition of the need to maintain roles and relationships with children that are comprehensive, dynamic, and differentiated.”
—Sara Lawrence Lightfoot (20th century)
