I've been doing similar research, but more on the focus of legislation for the care, and respect given to Military Working Dogs. During my research I found the "Logan Haus Kennel," a West-Virginia based kennel that supplies mostly military trainers with Belgian Malinois, the preferred breed for elite special forces. I would also look up "Trikos International."
Try giving one of these guys a call or e-mail and see if they can help you out with more of the information you're looking for.
