Kampfgruppe gegen Unmenschlichkeit

The Kampfgruppe gegen Unmenschlichkeit (KgU) (German for "Combat Group against Inhumanity") was a German anti-communist terror- and resistance group based in West Berlin. It was founded in 1948 by Rainer Hildebrandt, Günther Birkenfeld and Ernst Benda and existed until 1959. Rainer Hildebrandt would a few years later establish the legendary Checkpoint Charlie Museum.

The KgU received significant financial support from several Western intelligence agencies as well as the government of West Germany and the Ford Foundation. The US Army's Counterintelligence Corps (CIC) provided funding from the group's creation in the late 1940s. By the early 1950s, the Central Intelligence Agency (CIA) gradually replaced the CIC as the KgU's most prominent American backer. According to CIA documents, the KgU ran approximately 500 agents in East Germany in the early 1950s, which, according to historian Enrico Heitzer, put it on par with the Gehlen Organization, the predecessor to the West German intelligence service Bundesnachrichtendienst.

The KgU's activities included sabotag, arson and poison attacks as well as aggressive economic warfare which intended to cause a "breakdown in the whole [East German] administrative system", such as Operation Osterhase ("Easter Bunny"), in which the group sent 150,000 fake letters to East German stores, ordering drastic price cuts in order to cause a run on already scarce consumer goods. Other activities included collecting data on individuals imprisoned in East Germany and passing it on to their relatives, as well as collecting names of informers to the East German government and passing it on to RIAS, which would then broadcast so-called "snitch reports" in order to silence informers and discourage others from engaging in similar activities.
