 The name of the exercise is Raiku Vice-21. So this is Max-Force 1st Air Defense Centric Exercise that we're doing on Island here in Okinawa. Really what we're doing is providing aviation command and control services for fixed-wing aircraft. So for this specific exercise, we got VMFA-121 and 242 from Iwakuni. Those are your F-35s. And then we also have on the Air Force side the 9-61st AWACS. And then we have 67th and 44th Fighter Squadron, which are F-15s. So really what we're doing is running two missions a day, mixed between offensive, defensive, counter-air type, live flight scenarios, where the aircraft, they go flying the local range spaces here in Okinawa. And then us down here in the tactical air operation center, we've got Marines providing air intercept controller services, and then other aviation command and control services in support of those aircraft.
