Personal defence kit ?

[grumpy old man]

the thing with most martial arts is you have to do them and put the hours in training the better you become the more you learn and understand, ju jitsu is one of the oldest forms going back before 700ad through all the battles every army uses a watered down version so their troops can defend them selfs when unarmed but until you grade up passed black belt you wont know the counters so when the new forms like krav maga or systema or used great until you come across someone who knows what their doing remember for every move there is a counter and a counter for the counter a black belt only says you know the basics the first step (sho dan) and will take you about 4 years to get there best stick with a gun if you harts not in it
