I don't think it's #1, but I figured We Were Soldiers would have made your list somewhere.....
Thrash me good, Mike! I completely forgot about Mel Gibson's most excellent We Were Soldiers. It showed, like no current films I know of, that a very religious man can make an excellent warrior.
Besides the very effectively presented combat scenes, the segment when the wives were delivering the telegrams worked on my emotions like few films have ever done.
I forgot "We Were Soldiers Once". Thanks.
