+1 Breaker Morant

There are some great scenes in Farewell to the King, in general one of my favorite niche movies. But they are far more IW / SF or something else other than COIN.

You asked re copyrights. I attempted one time to get legit permissions for use of a clip from the Siege for an official homeland defense presentation. It is an unbelievable nuisance. You have to get multiple permissions from the studio, the individual credited actors who are on screen in the clip(s) you intend to use, etc. etc. Even with a Hollywood LnO, it proved untenable in our timeframe. In my naivete I figured it must be doable. It probably is, but too hard for 99%+. I now understand why the "don't do it" and "don't ask" COAs are so popular.

Here's a good resource on copyrights, http://fairuse.stanford.edu/
