Docm pretty much summed it up in terms of how the life of a soldier was like, as an enlsieted man no one really cared for you, sleeping in the cold and rain most of the tie, food shortages, disease, surgery, the enlisted man was constantly under hardships with little to no reward. The only highlights for soldiers really were when being commanded by men you could trust, who were charasmatic and who understood the soldiers life, victories were morale boosters too. But like many soldiers throughout history, in the army you're a hero during wartime, when the wars over, no one could give two shakes of a lambs tail what happened to you.
Theres alot more too it than that but thats just a rough summary.
