Colombian air force Brig. Gen. Sergio Andrés Garzón Vélez, PAMAMAX Combined Forces Air Component Commander, explains his expectations to the air forces participants for the upcoming PANAMAX Exercise at the base theater on Davis-Monthan AFB, Ariz., July 26, 2016. Nineteen total nations are joining the United States for a seven-day exercise that will use simulations to command and control multinational notional sea, air, cyber and land forces defending the vital waterway and surrounding areas against threats from violent extremism and to provide for humanitarian relief, as necessary. The PANAMAX exercise goal is to increase the ability of nations to work together, enable assembled forces to organize as a multination task force and test their responsiveness in combined operations.
