How about the CSI franchises? Or NCIS even? These show good and evil and how the fight goes on....

I agree about how fabulous "Battleground" is . 12 O'Clock High is an outstanding study in command. I also suggest "Pork Chop Hill" ,if for nothing else, a great story about perserverence in the face of hopeless odds and stupidity of "negotiating" with monsters at the fiat of fickle State.
