Kore Defense Industries LLP

Kore Self Defense is Kore Defense Industries’ physical training center located in Loudoun County, Virginia providing self-defense training built from a Krav Maga Curriculum originally developed by Eyal Yanilov. Building from this foundation, our curriculum is fueled by continuous research in the evolution of conflict and violence in the post-modern world. Unlike other Krav Maga based programs, our goals are not based on a systemic martial arts paradigm. We focus instead on what is relevant to our students now – today.

Krav Maga & Chiron Training

Krav Maga is our “hardware” and reality based self-defense is our “software”. Our Program Developer & Owner works collaboratively with Chiron Training & the International Violence Dynamics Team to keep our principle based self-defense training program relevant, effective, and current. Once certified, our instructors are required to continue their training; keeping their physical and instructional skills current. Like Karate, Brazilian Jiu Jitsu, and other martial arts, students can train and test for ranks designated by patches as a nod to our military history.

Before you step on the mat,
we encourage you to meet our team.
