Zhukov is known for being a damn good commander and beating the Nazis. Not for being a communist.
He joined the Communist party during the revolution and was a politburo member later in his life.
Look at his performance at the Seelow Heights, where the preparatory bombardment turner the Oder river bank into a sea of mud almost impassable to Soviet tanks and he ordered desperate frontal assaults simply to keep up with the Ukrainian Front commander's assault from the south.
