Krav Maga is a hype to sell Israeli arts,we all know that.
The Israelis have sold themselves as experts in battle ,in security,in Body guard work,in airline security,they are cashing in all around,and aside from the airline industry I do not think they are the best in the other fields,but the consumer does not know ,they know the hype.
Haganah is a different blend of KM than the TMA version which was the most popular,but how many recreations are people willing to pay for,as said it is not new materials,but a different version of what KM has been.
Haganah is a a variety of KM which is newer to most people,and it is built around Money making period.
The following is what Mike told me about 18 months ago:
To be an instructor You are supposed to have an existing school with a minimum number of students.(future purchasers of the DVD sets you must sell)
You get invited to the Instructor course which is 50 hours of training with Mike.
(this is the complete course for full certification)
You then go home with your certificate,your instructors package and I believe it was 40 sets of the DVDs to sell to your students( to recoup some of the money spent for the training)
To stay an active member and affiliate you are required to purchase and sell ,I believe it was, 4 DVD sets per month.
The course is taught in blocks,1 Block per month,4 Blocks(4 Months) makes a complete course.
You are to remind the students that 1 month per block does not make them proficient,it is just an understanding,to make the system work requires them to dedicate many more Blocks,(several years)
The course is sold to students in a complete 4 month package,they pay for the 4 months,either up front or payments,and then they may leave or sign on to redo the 4 Block series.
Each participant in a series of blocks is required to buy the DVD set.
You as an instructor may not make Instructors,you can have associates under you in your school but only Mike makes instructors and each needs their own school of so many students and then go through the course and sell the DVDs.
Being an Instructor and selling the DVDs gets you listed in the magazines and on the web site.
As I said,as far as what is sold as KM,Mike's Haganah is a better choice as it is more doable and eliminates the exchange,(sparring mode) some KM have gotten into,I also like Moni Aiziks Combat survival KM version as it is more in line with the basic Jujitsu type moves that were used in WWII combatives as taught by Fairbairn,Sykes,Applegate and others(US Navy and Marines,for Trembula),(Moni's has alot of fine motor skills that may not be doable under pressure,depending on the person,but there is enough material to find a doable solution as in Mike's Haganah )
Newer,different versions of KM,that is the flavor of the Day.
(The Israeli courts,years ago,said all Martial Arts in israel are allowed to be called krav Maga,so I expect to see many more versions)
It is all about quickly creating schools and instructors and selling the videos/DVDs,saturate the market and spread the hype,create a Buzz and a need, and SELL,SELL,SELL.
