Soviet Civil Defense Troops played the main role in the massive disaster relief operation following the 1986 Chernobyl nuclear accident. Defense Troop reservists were officially mobilized (as in a case of war) from throughout the USSR to join the Chernobyl task force and formed on the basis of the Kyiv Civil Defense Brigade. The task force performed some high-risk tasks including, with the failure of their robotic machinery, the manual removal of highly-radioactive debris. Many of their personnel were later decorated with medals for their work at containing the release of radiation into the environment, with a number of the 56 deaths from the accident being Civil defense troops.
