 Air Defender is the largest air exercise since the end of the Cold War and it's unique for us to be a part of this large exercise working with our NATO partners up to 25 nations I think a 10,000 personnel total and over 240 aircraft so it's a very big exercise and it's an honor for us to be part of it. For us it's just a fostering those relationships with our NATO partners. It's a German, Germany's our host but we're getting to work with I think 25 other nations in total and this is the best time to get together and to you know exercise those skills. It's like a large force exercise if you would think of something like Red Flag out of Nellis but at an international scale so it's an even bigger exercise. We like to say train like you fight and that's a you know it's kind of a maybe an overstated thing but it's really in my 25 years in the Air Force I don't think I've ever been on a single deployment where it's just been unilateral just the United States. It will always been in some capacity either a joint or combined force with some other nation or some other service so getting to do it out here on their turf and getting to work with them out of our comfort zone of our own home base makes us that much better.
