Been a while

Hey all, sorry I've been absent from the forum, I got married last month and of course this past week was Thanks Giving. But I'm back and have a good question for SSW or DS Clark. Did Da Shifu ever teach anything to our nations military/federal agencies? Specifically special forces type groups like Delta, Seals or Green Berets? Or perhaps he did some training for our C.I.A. friends? Just curious...
