Free Active Shooter Video
With Gershon Ben Keren


This is a short 10 minute video looking at some simple ways to actively counter, an active shooter should you find yourself dealing with such an incident. The solutions presented are deliberately simple and straightforward, and ones that can easily be learned and applied from watching a video. Some straightforward solutions are also put forward as to how to increase your survival chances. The solutions described in this video, make up a very small and specific part of countering and dealing with active shooter incidents, and should not be taken as a comprehensive approach to dealing with such killers.

Krav Maga Yashir Books
By Gershon Ben Keren


"Krav Maga - Real World Solutions To Real World Violence" is an Amazon Best Seller, which provides an honest and unfiltered look into how real-life attacks and assaults occurs, and how to identify, avoid, predict and prevent them, or as a last resort physically deal with them. Techniques were filmed, in the locations where such attacks are likely to be committed rather than in a gym or studio. The techniques demonstrated were all filmed in real-time, so none of the photographs were staged as stills. To read more and see sample chapters please click here.




"Krav Maga: Tactical Survival" looks at a variety of different scenarios to those presented in, "Real World Solutions To Real World Violence", as well as variations that an attacker can make to change the solution required. Although a follow up book, and already an Amazon Bestseller, it stands alone as a distinct work looking at particular forms and types of violence.
