U.S. Marine Corps Maj. Jose Jurado, Lt. Col. Joseph R. Faller, Maj. Michael Kingen, Lt. Col. Eileen C. Donovan, Capt. Nicholas M.B. Patinos, Capt. Jeffrey C. Abercrombie, and Lt. Col. Justin Carlson, all gather for a group photo in support of Keen Edge at Joint Base Pearl Harbor-Hickam, Hawaii, Feb. 1, 2022. Exercise Keen Edge is a joint, bilateral command post exercise designed to facilitate interaction between and improve the interoperability of U.S. Forces and the Japan Self-Defense Forces. Keen Edge proves our ability to effectively and mutually respond to a regional crisis situation that might have direct and immediate impact on both countries. The U.S. and Japan Alliance is the cornerstone of peace and security in the Indo-Pacific, supporting a rules-based international order that promotes regional stability and prosperity.
