I am an avid reader of such history but it's hugely weighted towards the Allies. I have read "Soldaten" (in translation), but found it a bit biased: all quotes are selective because they are the quotes that the British felt worth keeping when trying to prove war crimes. Accurate? Probably. Representative? I doubt it.
Entschuldigung, ich Sprache bissien Deutsche. Which ought to be enough to convince anyone that I need a good translated work.
I should say East Germans in the Cold War. I have read "Staziland" and found it interesting but the author seemed unable to get much personal access.
Hans Van Luck's memior--Panzer Commander--is a commander's eye view of the war. He saw action in nearly every theater, having served in Poland, France, North Africa, and the Eastern front.
I found Soldiers: German POWs on Fighting, Killing, and Dying by Sonke Neitzel and Harald Welzer to be very interesting, and at the same time quite disturbing. This book summarizes thousands of recordings of German POW's, including their views on atrocities.
Forgotten Soldier by Guy Sajer is a problematic book, but an interesting one nonetheless. There are certainly some inconsistencies, but I find most of his narrative to be plausible.
If you want a movie, the 1993 Stalingrad is heart-crushingly good. I believe the current versions offered have English subtitles available.
