Movies to watch that portray military leadership?

My JROTC instructor wants us to select and vote a movie to watch for 20-30 minutes that portray military leadership and the 14 Leadership Traits.

They do not have to be American military related, but they have to be in English. No subtitles please, all ratings are okay, and preferably free to watch on streaming services such as Netflix, HBO Max, YouTube, etc. except for Amazon Prime as the majority of movies are not free 😔

Please leave your recommendations, if you'd leave a trailer or an overall summary of the movie
