Lee wasn't in the military, but he's always game for a contact with reach he doesn't have, skills he doesn't have, etc. Favors for Favors. He's a Watcher right now, but before that traveled extensively as a Hunter with his twin sister. Easy to fill in previous run-ins or they could be new contacts. (I peeked at his bio - they both have a touch of the hero complex - that could be a thing also)
