Avengers: Red Taped
The Strategic Homeland Intervention, Enforcement and Logistics Division, better known by its acronym S.H.I.E.L.D., was originally a United States extra-governmental military counter-terrorism and intelligence agency, tasked with maintaining global security.
Founded in the wake of the Allied victory over the Axis powers and HYDRA in World War II, S.H.I.E.L.D. was organized to protect the United States, and later the entire world, from all possible threats. With its advanced weapons and extraordinary agents, S.H.I.E.L.D. was once possibly the greatest military power on Earth.
In 2014, through the actions of Captain America, the world became aware of the fact that S.H.I.E.L.D. was infiltrated and largely controlled by the terrorist organization HYDRA. After the battle in which S.H.I.E.L.D.‘s primary headquarters, the Triskelion, was heavily damaged, all of S.H.I.E.L.D.’s classified files were dumped on the Internet, and the agency was disavowed by its commanding governments and labeled a terrorist organization. Many agents and officials were taken into custody and subjected to rigorous questioning, and S.H.I.E.L.D. was dissolved.
