 All right, looks like they're starting to set up. We're out here validating the defensive air combat maneuver with the Apaches and utilizing the Marine Corps weapons and tactics instructors to kind of call up some of our SPs for the Apaches so we can write the ATM task for aviation. Right now what they're doing is the first couple line numbers of this type of maneuver. Our orientation so they can kind of get used to going through the basic maneuvers of an aircraft, an adversary is trying to attack you, another helicopter. So that's what they're going through right now is how to defend against that and get into a position to engage. It's part of the aviation tactics transformation that's currently ongoing in USACE. Part of it is specifically the line of effort number three which is the aviation tactics instructor course. So in order for that course to mature we're in the production right now so we've identified a couple key tasks that we haven't had written for army aviation. That's why we're out.
