The higher commander who goes to Field Service Regulations for tactical guidance inspires about as much confidence as the doctor who turns to a medical dictionary for his diagnosis.
A general may succeed for some time in persuading his superiors that he is a good commander: he will never persuade his army that he is a good commander unless he has the real qualities of one.
A bold general may be lucky, but no general can be lucky unless he is bold. The general who allows himself to be bound and hampered by regulations is unlikely to win a battle.
