Try General George Patton. His philosophy of war was centered around flexibility and changing the plan to fit the circumstances instead of the other way around.
He spoke the language of the people he was addressing. That's why he cussed in front of the troops - they really understood him. In more senior company he could be mildly profane but charming and very erudite on a variety of subjects.
Patton, despite all his shortcomings, was actually a remarkable leader of unusual quality. He was extremely well read and the author of several military papers on strategy and tactics. He was probably the best motivator of men the army ever produced. He was tough on himself and his men, and above all he was successful.
