I know I have a soft spot for military/military related movies being a veteran and coming from a military family so I may be biased but if y’all don’t mind an older movie check out The Best Years of our Lives. It came out in 1946 and is about 3 guys from the same town returning home after WW2 and picking up where they left off.
It may sound like a boring premise but I promise it’s an excellent movie. I know it’s currently available on Pluto TV.
I enjoyed Good Morning Vietnam. Robert Heinlein is one of if not my all time favorite author. I do enjoy books over movies as well. Golden age of sci-fi is great. Modern day “sci-fi writers” crap on that era constantly
