 Citino credits Rommel's limitations as an operational level commander as "materially contributing" to the eventual demise of the Axis forces in North Africa, Meanwhile, Addington focuses on Rommel's disobedience and struggle over the North Africa strategy, whereby his initial brilliant success resulted in "catastrophic effects" for Germany in this theatre of war.The historian Geoffrey P. Megargee refers to Rommel as a "talented tactical leader", but points out his playing the German and Italian command structures against each other to his advantage.Rommel used the confused structure of the OKW (Supreme Command of the Wehrmacht), the OKH (Supreme High Command of the Army) and the Italian Supreme Command to disregard orders that he disagreed with or to appeal to whatever authority he felt would be most sympathetic to his requests.
