This text is the second of three volumes written by Colonel Glantz on the contribution of intelligence and deception operations to the Soviet victory over Nazi Germany. It examines the area where intelligence and operations overlap; the nature of co-ordination between the two; and the support provided by intelligence to operational planning and execution (or the absence of such support). This is not a study of intelligence work as such, but of how intelligence can improve the chances of success on the battlefield by facilitating the more effective and economical use of troops.
