The nation that will insist upon drawing a broad line of distinction between the fighting man and the thinking man is liable to find its fighting done by fools and its thinking by cowards.
-- Sir William Francis Butler
A 2011 Air Force chief of staff reading list selection, Technology Horizons assesses what is credibly achievable from a technical perspective to give the Air Force capabilities suited for the strategic, technology, and budget environments of the next two decades. While visionary, its view is informed by the strategic context in which these technology-derived capabilities will be used. It has sought to envision not only US joint and allied opportunities for using technologies, but also ways that adversary capabilities could be derived from them using entirely different concepts of operations or war-fighting constructs.
