Asymmetrical Defense believes in making Americans more prepared to defend themselves should the unexpected happen.


 We believe that because the Bill of Rights grants us as Americans the right to keep and bear arms that we must do so responsibly.


 The way we build responsible Gun Owners is by offering professional training building self-sufficiency and a more aware society.


Asymmetrical Defense was created to provide professional training to U.S. Citizens, Law Enforcement Officers and Military Members alike in order to better prepare oneself should an emergency arise.  We focuses on providing practical solutions to sometimes complex issues such as firearms training, concealed carry, first aid “dirt medicine”, defensive tactics, personal preparedness and much more.
