Battles of Khalkhin Gol
At least three elements, namely deception, concealment, and disinformation with false defensive works and false troop concentrations, were used by Georgy Zhukov in the 1939 Battles of Khalkhin Gol against Japan. The deceptions included apparent requests for material for bunkers, the broadcasting of the noise of pile-drivers and wide distribution of a pamphlet "What the Soviet Soldier Must Know in Defence". In his memoirs Zhukov described them as such, noting that they were worked out at army group or "operational-tactical" level.
