I think the guy is covering a Swastika, it does loooks like a Swastika behind the Red dot of death.
German soldier falls to his death after being shot by a Russian sniper seconds before.
Its actually a video it seems.
"In the video,the cameraman is right next to the sniper when he shoots,then it goes to the scope view as shown here. Im guessing he either moved to the shooters scope quite fast,or had another sniper rifle present that he was using to get the scope footage. Which does not suprise me giving how much the Red Army used their snipers for propaganda "
