In CCU Founder Pat Kilchermann's first book, published here in 2020, he sets forward a powerful formula for hardening your home and readying yourself for home defense, using what he calls the 4 Layer of Home Security.
"The outer two layers are all about Deterrence: making them avoid ever targeting your home to begin with. But if those fail, your inner layers kick in: first, to make sure you KNOW your home is being targeted and to buy you time so that you have time to arm yourself and gather your family - and then so that you know exactly how to engage a violent intruder inside your home. I cover all the tools, firearms, and gadgets that can help you accomplish these goals. I think you'll love this material." - Patrick Kilchermann, March 2020
