About the Viking KAPAP self defence group

So what is Viking KAPAP?

Viking KAPAP, previously KAPAP Great Yarmouth, opened it’s doors in 2012 by the club founder Brett Mackenzie.

Starting from the beginning, in the early days, Brett was shy and very withdrawn. He had suffered a lot of bullying at school, so as a young man at the age of 13 he started karate classes. At the age of 14 he decided to join the army, he was determined to join the infantry and that was that.

The following few years were tough and he learned to do and see things he didn’t like doing, but he would roll up his sleeves and just get on with it. Over the years his mindset changed and he discovered an inner toughness and resolve. He served with the 1st Battalion Royal Anglian Regiment for several years seeing active service in Northern Ireland in the the late 80s and early 90s.

After leaving the army, Brett continued to study martial arts (freestyle karate) and was encouraged to work the doors in Great Yarmouth. It was at this point he moved into full contact Muay Thai/K1 with a good friend of his Trevor Lowe. What followed was several years of very hard training and conditioning that he learned to really appreciate. He later returned back to Karate and eventually earned his black belt after a very long journey and for several years taught classes in Great Yarmouth until he stopped due to ongoing injury issues.


Searching for something different

After researching the market he stumbled across a little known martial art at the time called ‘Krav Maga’, the nearest club was in Colchester. This involved a lot of travel and whilst learning ‘Krav Maga’ Brett came across an even more little known system called KAPAP and that really interested him.

After doing his homework, he decided this is what he wanted to do. So in 2012 he took the plunge and started making long journeys to Bridlington to learn KAPAP, meeting his teachers Sam Markey and Chief Instructor Avi Nardia.


GROM Practical Shooting Academy Serbia

In 2015 Viking KAPAP joined Avi Nardia’s recommended firearms academy GROM Serbia under the tutelage of Master Željko Vujčić. Something Brett had really missed since leaving the Army was shooting, Brett loves visiting Serbia, the people, the hospitality and the range culture. He feels at home and regularly brings students over and teaches under the GROM banner.

If you really want to do something you will find a way, if not you will find an excuse


Only human, Brett considers himself to be nothing special. He just didn’t give up!

Brett, since his 40s, has been blighted with injuries and continues to train. Recently he has had a full right hip replacement and that his not going to stop him. He continues to train and understands limitations and at present is a student of Japanese Jiu Jitsu and continues to teach KAPAP and practical shooting.

Very eye opening to the severity of violence, nice basic principles to follow. No painting by numbers as it were, would recommend to anyone looking to survive and protect the ones you love. Given that the circumstances are correct, no nonsense no bullshit training, coached by a very experienced guy. On a person level, I have trained for over a year and it's has helped me or than once with surviving a fight or two. Plus, A side perk of the training is you keep fit, mentally and physically.
