Part of that comes from the fact that one of those women who have been in combat situations was one of the WP nieces, serving a tour in Afghanistan in hostile territory and working as a buffer between Special Forces and Afghan women. The story of such missions can be found here.
Included is this TED talk video covering this program.
We kept a candle lit in our window for our niece until she came home safe. One of the happiest and proudest days of my life was the day we were able to take it out of our window because she had returned home to us.
