A good friend from my work, who was an Armor Master Gunner instructor for the Army, a veteran of the combat in Kuwait and Iraq in 1991, recommended _The Forgotten Soldier_ by Guy Sajer, published in 1965, if I wanted some details regarding what combat was like for a person serving in the military. It grew out of a conversation we were having regarding what soldiers had to endure in addition to operating an airborne delivered, air droppable tank (M8 Armored Gun System) I was helping to develop logistics support for during its research development phase. The issue was how much of a cognitive burden a soldier could bear while looking at the information displays and operating the controls to fight the tank (called MANPRINT in the US DoD). The book painted a pretty stark picture of war for a young soldier from Alsace drafted into the German Army and sent to fight on the Eastern Front with the Grossdeutschland Division and then shifted back and forth from East to West to combat following Normandy invasion and then to protect the German borders. I've since seen some criticism of the book's authenticity, but given that Sajer was less than inspired to learn about Nazi dogma, and wasn't a far up in the command chain, there could be some confusion regarding places and military rules that got confused in the 20 years after the war ended.
