S.A.B.E.R. is a mysterious secret organization led by Nick Fury in the Marvel Cinematic Universe. It appears to have been set up after the events of The Blip and operates as S.H.I.E.L.D. in space, protecting the Earth from extraterrestrial threats like Thanos. S.A.B.E.R. is a branch of SHIELD, Marvels counter-terrorism and intelligence agency. It is a space battle station designed exclusively to look after extraterrestrial threats and stand as a first line of defense against any such adversary of alien nature. The full form of S.A.B.E.R. is still unknown. S.A.B.E.R. is not the same thing as the previously established SWORD, which is responsible for protecting Earth from everything that comes from other dimensions. The Marvels’ trailer suggests that it is S.A.B.E.R.’s job to search for anomalies outside of Earth, which should be SWORD’s job. However, S.A.B.E.R. may be an extension of SWORD, perhaps a special space station with specific purposes. The similar style of acronyms, which also tie into SHIELD, adds to that idea.
