The comissars were executed by the Wehrmacht or the Waffen SS in the frontline that was given and given by military orderSorry forgot description of these:
1) a small hill or mound is no protection from German shrapnel. This commisar (see his stripes) got a lil off the sides...lol
2) russian machine gunner took one right between the eyes
3)someone quite rotten with a large entry wound
4) 2 unlucky russian tankers
Although it appears in the picture that the commissar died during the fight, he would have been killed in any way
