Hapkido

Hapkido is the most comprehensive self-defense system on this list, emphasizing joint locks, throws, and kicks in fluid, circular techniques against armed and unarmed attackers. Instructors trained Korean military, police, and presidential security detail throughout the 1960s and 1970s, proving its practicality in high-stakes environments. Its defensive breadth is more complete than #3 Tang Soo Do's linear striking focus, and it remains a top choice for law enforcement professionals.
