Military personnel facing a first TDY or assignment to a U.S. Embassy abroad are often concerned about how they will fit in, and more importantly, succeed in an unfamiliar environment. It is true that a typical U.S. Embassy works very differently from the Pentagon, Fort Bragg, or Naval Base Coronado. But you don’t need an Enigma machine to crack the diplomatic code and find success; all it takes is a little background and preparation. As an FSO for 35 years who retired as U.S. Ambassador to Kosovo, Greg Delawie spent the majority of his career working closely with U.S. military personnel from all services and many specialties, both in Washington and at posts abroad and offers insights to help empower incoming military personnel to transition smoothly into diplomatic culture.
