Very hard to tell what's going on here. Allow me to take an intelligent guess: a wafer SS soldier was crawling next to a dead Soviet soldier who might have been killed recently (to his left), and part of his cloth had been removed by this SS soldier. The weather could be early in the winter, say, November, as you could clearly see the frosts on the ground. The SS was still in his summer uniform and it could indicate the year being 1941. The quilted jacket could be for himself?
