Assassin's Mace

Concept

Let your plans be dark and impenetrable as night and when you move fall like a thunderbolt.
— Sun Tzu (孙子)

The Chinese version of David and Goliath involves the hero using an 'Assassin's Mace (杀手锏) which, despite being small and lightweight, could be used to surprise the enemy knocking him dead with a single blow to his Achilles' heel.

Application

China is focusing a disproprortionate amount of its resources on asymmetric capabilities such as cyber attacks, anti-satellite weapons, electromagnetic pulse weapons, ground-launch missiles to combat America's superior long-range bombers, ground forces and nuclear armed ICBM's.
