U.S. Air Force Senior Airman Vincent Polizzi, 736th Security Forces Squadron fire team member, Andersen Air Force Base, Guam, watches from a defensive fighting position during exercise Tropic ACE Aug. 31, 2017, at Kadena Air Base, Japan. ACE allows us to move forces more fluidly across the theater to seize, retain, and exploit initiative against an adversary, and exercising this capability is key to ensuring readiness and resiliency.
