German military counterintelligence has discovered several potential neo-Nazis in the country’s Tier 1 Special Operations unit.

According to German media reports, the Kommando Spezialkrafte (KSK), an equivalent to Delta Force and the British Special Air Service (SAS), has been infiltrated by neo-Nazis. At least one operator has been kicked out of the unit and two more face a similar fate.

This isn’t the first unit that the KSK has been investigated for far-right infiltration. In 2017, similar suspicions had been raised, without any consequence, however. And earlier this year a seasoned KSK operator was also kicked out over connections with a far-right organization.

In the last few years alone, Militärischer Abschirmdienst (MAD), the military counterintelligence, has opened more than two dozen investigations relating to far-right extremism into the unit.
