If our military history has taught us anything, it is this: war, and how we defeat our enemies, evolves over time. As our global adversaries develop new tactics and weaponry, and engage in long-term strategies to usurp U.S. national security, our National Defense Strategy requires us to meet these threats head-on to protect what matters most – our freedom. We must train to develop agile, innovative, and ready Airmen Engineers who are prepared to tackle a complex global environment. Exercises like COPE North 2020, held at Andersen AFB, give participants the opportunity to train in a joint environment, testing combat readiness and simulating a real-world situation. This trilateral field training exercise incorporates joint and combined U.S. Pacific Air Forces with participants from the U.S. Air Force, U.S. Navy, U.S. Marine Corps, Japan Air Self-Defense Force (JASDF), and the Royal Australian Air Force (RAAF).
