S.H.I.E.L.D

S.H.I.E.L.D. (Supreme Headquarters International Espionage Law-enforcement Division) is an extra-government intelligence and security organization dedicated to protecting the nations and peoples of Earth from all threats, terrestrial or extraterrestrial. S.H.I.E.L.D. was organized in the early 1960s to meet the threat of the highly technological subversive organization called Hydra. The identities of the organization’s founders, its Executive Board, have never been revealed. S.H.I.E.L.D.’s first known Executive Director was Colonel Nicholas Fury, an ex-World War II commando and C.I.A. operative. S.H.I.E.L.D.’s Supreme Headquarters is the huge mobile Helicarrier, but there are also regional offices in all the major cities of the free world and several secret bases in Communist countries. Although most of S.H.I.E.L.D.’s operations are covert, the organization’s existence is known to general public. S.H.I.E.L.D. even maintains public offices in several cities.

Only a few of the several thousand S.H.I.E.L.D. operatives active throughout the world are known.

In the wake of Colonel Nicholas Fury's "Secret War" the position of director was passed to Maria Hill.
Recently she has passed the role to Tony Stark (Iron Man) after the "Civil War".
