The Best Years of Our Lives (1946)

We started watching this movie a couple of years ago, back when we were trying to see all the movies that won best movie Academy Awards.  We got about 45 minutes in and then never got back to it, but in all, it is an excellent movie about the transition of servicemen back into civilian life post WWII.
There are three threads, one of which is the effects of war on a family.  Fredric March was a banker before he went to the European theater and he is one when he comes back.  His experiences in war leave him feeling like what he does in his job is fairly trivial, and he has trouble readjusting to civilian life, but is fairly well off with a wife and child who welcome him home.  Hoagie Carmichael is a sailor whose ship went down and he was amongst a few survivors.  He lost both his hands, which he struggles with fitting back in, despite his family and fiance welcoming him whole heartedly.  He finally accepts that he can have the life he left behind and gets married before the end.  Dana Andrews is a guy who was unskilled before he went to war, was a hero there, performing well under pressure and then coming home with PTSD and no job prospects.  His wife has also moved on without him, and to a large extent, his story seems pretty comparable with modern soldiers.  Really, a great film, maybe a tad on the long side, but well worth watching.
