This team appeared in the films Captain America: The Winter Soldier (2014) and Avengers: Endgame (2019). This version of the team were actually undercover Hydra agents. In various MCU film and television appearances, S.T.R.I.K.E. is a unit within S.H.I.E.L.D., not an independent organization.
S.T.R.I.K.E.'s original headquarters, as seen in the organization's first appearances, was an undersea air base which contained several of S.T.R.I.K.E.'s planes that were considered superior to their American counterparts at the time.[1]
S.T.R.I.K.E.'s Psi division had their own headquarters.
Another headquarters was in a closed university, located in London, England; this headquarters was later used by D.U.C.K (Department of Unknown and Covert Knowledge).[2]

Known members
Colonel Elizabeth "Betsy" Braddock[9] - a mutanttelepath from the S.T.R.I.K.E. Psi-division who was possessed by Proteus and died in the ensuing conflict with the X-Men. Her consciousness came to reside in the body of a young comatose girl known as Kwannon.[10] While inhabiting her new body Betsy was technically considered a minor and was thus unable to work for S.T.R.I.K.E. She worked undercover for Charles Xavier for a time, eventually joining the X-Men.[11]
