The Combat Organization (Russian: Боевая Организация, romanized: Boyevaya Organizatsiya, or the Fighting Organization) was the terrorist branch within the Socialist Revolutionary Party of Russia. It was a terror sub-group that was given autonomy under that Party. In his memoirs, group member Boris Savinkov called the group the "Terrorist Brigade."^[1] (This phrasing was followed in his own memoirs by Whittaker Chambers, an American spy for the Soviets.^[2])
