The research question of this thesis was to explore exactly how the Reichsheer leaders transformed their warfighting doctrine. This thesis also looks closely at the underlying organizational philosophy, and how the philosophy guided the Reichsheer leadership cadre in affecting change within the organization. Reichsheer doctrinal manuals, directives and contemporary journal articles, supplemented with American observer reports, served as primary source material for the thesis. The thesis will clearly link the importance of a leader creating and articulating an envisioned end state in successfully effecting change within a military organization.
