"Every action is seen to fall into one of three main categories, guarding, hitting, or moving. Here, then, are the elements of combat, whether in war or pugilism"

This quote by B. H. Liddell Hart is describing the 3 primary classifications of action in combat. These classifications are protecting, striking, and moving. Guarding is the act of protecting oneself from an attack, while hitting is the act of assaulting an opponent. Moving is the act of altering one's position in order to get a benefit. These 3 categories of action apply to both war and pugilism, or boxing. In war, soldiers should safeguard themselves from enemy attacks, struck the opponent with their own weapons, and move tactically to acquire an advantage. In boxing, the same 3 categories of action are utilized. Boxers must guard themselves from their opponent's punches, hit their opponent with their own punches, and move tactically to get a benefit. In both war and pugilism, these three classifications of action are essential for success.
