I agree.
Extreme situations (and war has more than its fair share) can bring out amazing or outstanding qualities in the human race.
I am largely unaware of a lot of U.S. acts, and have mostly studied British history, but defy any serving or former serving person not to be captivated by some stories from the U.S.
The story of Roy P Benavidez is one such story of going above and beyond what is expected!
