Yes Jean you are correct, Vlasov did indeed due his part in the Battle of Moscow.

however he switched sides to fight with the Germans and shot at his own people ( Russians )
For this reason, it is the Russians who consider him ( and rightfully so ) a traitor. Other's in other Soviet Republics try to either excuse or lesson his crimes....

~Strik-Strikfeldt, who had been a participant of the White movement during the Russian civil war, persuaded Vlasov to become involved in aiding the German advance. Along with lieutenant colonel Vladimir Boyarsky, Vlasov wrote a memo shortly after his capture to the German military leaders, suggesting a cooperation between the anti-Stalinist Russians and the German Army.


Later in 45' he switched sides again during the Prague uprising and began fighting the Germans.... As you can imagine this did not sit well with Stalin or the people and he was executed in 46'.
