S.H.I.E.L.D.
Strategic Hazard, Intervention, Espionage Logistics Directorate
formerly
Supreme Heaquarters, International Espionage, Law-enforcement Division
The United States' first and best spy organization, run by Col. Nick Fury, of "Sgt. Fury and his Howling Commandos" fame. While its operatives work around the globe, S.H.I.E.L.D. is based in a floating fortress called the Helicarrier, which is a giant aircraft carrier held aloft by propellers and jet engines. S.H.I.E.L.D. are generally good guys, although their law-enforcement charter can bring them into conflict with the mutants, who usually have outlaw status. Recently, Fury designated Sharon Carter (Agent 13) to replace him while he is away on a mission. G.W. Bridge is also a member of S.H.I.E.L.D. and once took command of its operations when Fury was presumed dead.
