 So this mission is called Falcon Defender. It's a concept that was originally thought up about five years ago. We have implemented it for the second year in a row in Bulgaria with our state partnership program. We're trying to take things that we've learned and things we've been successful with and pass them on to the Bulgarian Air Forces. We really seem to love their initiative. They want to learn and that makes us eager to want to teach. The partners really have been official to both sides, both the United States and to Bulgaria, building additional alliances around the world in case we're needed and called upon. It's really the integration piece that the U.S. brings to that. It has been truly amazing to watch one of their culminating events today shoot, communicate, exercise as well as the TCCC, self-made buddy care, what a capstone exercise for those airmen. As an integrated force, U.S. and Bulgarian force.
