Many of the British Forces exposed to Eastern Martial arts,(Jap slapping/WWII type combatives), around the 1980's seem to have only kept some techniques and have continued the use of Milling,(Boxing with throw downs allowed) as the main stay art,which WILL DEFINATELY create a fight mind set.
It was also called Jap slapping because most in the British Forces are exposed to boxing,closed fist fighting and the Techniques used , of the Eastern Martial arts,like the mostly Jujitsu based techniques used open hands ,edge of hand strikes,Palm heel strikes ,which on lookers said looked like slapping.
I got exposure to Milling when training with the British in the mid 70's
I got exposure to what they called Jap slapping when working with the British in the 1980's and most didn't care for the Jap slapping they prefered Boxing/Milling with some kicks and knees allowed, lol
