It was hoped that in the event of a Soviet invasion these infected livestock would mingle with local herds to cause epidemics and to destroy food supplies. Unit 100 staff poisoned and drugged Russians, Chinese and Koreans with heroin, castor oil, tobacco and other substances for weeks at a time. Some died during the experimentation. When survivors were determined to no longer be useful for experimentation and were complaining of illness, staff told them they would receive a shot of medicine, but instead executed them with potassium cyanide injections. Executions were also carried out by gunshots.
