White émigré
The émigrés formed different organisations which had the purpose of fighting against the Soviet regime. Examples of such organisations are the Russian All-Military Union, the Brotherhood of Russian Truth, and the NTS. This made the White émigrés a target for infiltration by the Soviet secret police (i.e. operation TREST and the Inner Line). Seventy-five White army veterans served as volunteers supporting Francisco Franco during the Spanish Civil War.
