In August 1957 the report was written by a group of researchers of the Georgetown University at the request of the Department of the Army. The document fully analyzed prospects of carrying out anti-Soviet armed struggle in the Ukrainian Soviet Socialist Republic by the US special forces in order to orchestrate an anti-Soviet revolt.

The first region where the US special forces may get significant support are left-bank Poltava, Chernigiv and Sumy regions, as well as a right-bank Kirovograd one and part of the Vinnytsya region.
