Course Information

Knife Level 2 teaches American Kali, the premier hybrid combative system for the modern citizen warrior. Covering the combat spectrum from empty hands to firearms, standing to grounded, American Kali seeks to develop the fighting efficacy and unconquerable mindset necessary to survive deadly encounters. With roots in the same process that produced the legendary OSS fighting operatives and Marine Raiders of WWII, American Kali places a heavy emphasis on physical aggression, mental resiliency, and emotional stability.
