What religion/ethnicity were the executioners in the gulags of the Soviet Union system?

Answer 1

They came from all the constituent republics of the Soviet Union, from the Baltic across Russia and the Trans-caucasus to Central Asia.

The word "executioner" carries the idea of a person officially employed to carry out a legal state-sponsored killing. I  hope you're aware that vast numbers of prisoners in the GULag weren't officially "executed" but died of starvation, brutal treatment and inhuman levels of cold.

Answer 2

Travellers... travel agents... dispatchers... voyagers. This IS the TRAVEL history geographical section, you know.

Answer 3

Soviet union actually cracked down on religion as it rivaled worshipping the soviet leader as a god, so they were likely atheist or at least hiding their beliefs.

Answer 4

Atheist/non-religious, Russian Orthodox, Muslim, and other
