This study evaluates the military career of General Robert T. Herres. It analyzes two broad aspects that influenced him as a senior military leader: personal character traits and career diversity. The author assesses how General Herres' early diversity in jobs and character traits helped him develop the breadth and depth that would shape his performance as a senior leader. The conclusion suggests his career could serve as a model to encourage career diversity in the development of today's senior Air Force officers. The US Air Force should strive to develop senior leaders more broadly by challenging them with various educational, staff, and command experiences. The intentional development of senior leaders with wide-ranging backgrounds bolsters the cultivation for broad strategic perspectives within the Air Force. These well rounded leaders can transcend their major command and military service to integrate air and space power into support of our national security strategy.
