I am, but I was thinking more than just the obvious.

( of course doctors and soldiers would be needed in a war but they could have then recruited anyone. angela didn't know anything about this man other than what she could currently see, and even barring his physical appearance that wasn't much, but based on herself she had a few guesses )

Perhaps what we've done or how we've used our training is what they needed. Or somewhere that we've been. I've treated soldiers, and been on a battlefield before. Perhaps you have something equally as usual, more than any soldier may know.
