This SD unit was responsible for, among other things, falsifying passports and documents. Within the setting of Operation Bernhard, the SD forged pound notes in great numbers, funding Nazi Germany with ₤600 million in high-quality counterfeit currency (worth approx. $6 billion 2009). This counterfeiting operation was named after Krüger, who led the operation from a segregated factory built at Sachsenhausen concentration camp, manned by 142 Jewish inmates. Krüger was a member of the NSDAP.
