 Rommel often went directly to Hitler with his needs and concerns, taking advantage of the favoritism that the Führer displayed towards him and adding to the German High Command's distrust of him.Military practitioners have also questioned Rommel's abilities at the operational level.While nearly all acknowledge Rommel's excellent tactical skills and personal bravery, many officers came to accept that Rommel was "possibly the most overrated commander of an army in world history", writes U.S. major general and military historian David T. Zabecki of the United States Naval Institute, quoting the opinion of Wolf Heckmann.
