These courses are all about the universal essence of combat. The recognized "Hammer and Nails, Nuts and Bolts" of hand, stick, knife and gun combatives. They present the common problems and problem-solving you will encounter, on down to the uncommon ones.
From this experimentation and education you build your own "method, "approach," "style" or "system" and responses based on your own size, strengths and skill.
These terms are generic and semantic at some level. But I do not believe I teach a method or style. You make your own house from these nails, nuts and bolts.
