Combat reduces to stand-up, clinch, and ground ranges

Effective fighting should be understood as three ranges or delivery systems—stand-up (striking with a boxing base), clinch (fixed positions like underhooks and neck ties), and ground (any position you can fall into)—rather than as individual styles; best practices like a choke or a hip throw are universal across cultures, so there is no such thing as a 'Japanese choke' just as there is no 'Canadian geometry.'
