In 2019, US Army senior leaders urgently needed an organization to work with its partners and allies to meet White House-directed national security objectives. Green Light Go! provides a behind-the-scenes look at how the 5th Security Force Assistance Brigade (SFAB) formed and developed into this essential organization, eventually venturing off to the steppes of Mongolia, the humid jungles of Indonesia and the Philippines, and the pristine beaches of the Maldives. National security practitioners, leadership development professionals, and contemporary historians will be fascinated by these insights into the inner workings of a nascent Army organization as unit members navigate through complex obstacles. Never before has such an unlikely group been able to accomplish so much in a short time frame while capturing the essence of entrepreneurship.
