Modern Hapkido teaches techniques that take into account the fact that you may have to fend off an opponent and get items from your duty belt at the same time. Whether you are simply fighting and reaching for your handcuffs or drawing your sidearm, you need a martial art that recognizes that you have duties to perform that require you to be able to execute some techniques with one hand or that you need to switch from two handed joint locks to one hand to get to your weapons. Many martial arts teach relatively simple disarm techniques. Most do not consider weapon retention techniques at all. You need to keep control of your firearm, asp, mace, baton, etc. when under attack or even when you approach a subject who jumps from cooperative to hostile in the blink of an eye.
Many schools offer some moderate amounts of self defense sprinkled into their classes as an extra.
Our assumption is that you will have to control subjects who are violent, younger, stronger, taller, and faster than you may be. You will learn techniques that rely on skill and balance, not muscle and strength. You just add techniques to what defensive tactics you already know. If you are a kicker and striker, you will add chokes, throws and joint locks. Since Modern Hapkido is basically a set of practical techniques based on Judo, Jujitsu, Aikido, and Tae Kwon Do, there will be portions of our classes that are refresher courses for you , and parts that are new.
