my grandpa survied the battle of Reims in 1918 during WW1 and not enough of war he was also in Stalingrad serving in the 6th Army in WW2
He told me he saw the Hell on earth, he never went into deatail, but i was 14 and wants to know it all, so he described truly detailed that they were stopped attacking because the tank chains was full of frozen bones and bodies by dead soldiers, he told more and more details, he stopped when he saw my face, i must been very shockated, i just saw his tears running down, he stopped talking with a short phrase like, " no one could ever love life more than ones survied Stalingrad or the whole war"
So personal i don't think those pictures are something to laugh about
Your Grandfather getting through Stalingrad alive is a near miracle.Of the 100,000 plus prisoners taken,only 5,000 ever returned to Germany.Just watching the Germans being marched out of Stalingrad,hurts my heart!Hitler should have allowed Paulus to break out while he still could.Hitler's no retreat policy shortened the war by many years.I seen a picture of a older German soldier making a younger one hold his head up,that was gut wrenching.I didn't like the picture of the two German soldiers comforting each other,it wasn't about being gay!Bad taste in my opinion.
I'm not a Nazi backer,and my brother fought in WWII with the 36th infantry division.I support the soldiers,as most where just fighting for their country.The politics can go to hell.The Germans where the best defensive fighters the world has ever seen!
If you have never been in combat,please save the pictures meant to portray something that it wasn't.Seeing people being killed an maimed isn't pleasant,and a hug or a slap in the face are some of the ways to bring a soldier out of his shock.

to your Grandfather,a very lucky warrior!,and thank you for sharing.
