i’ve heard that krav maga is some of the most hardcore hand-to-hand counter-attacking in the world. i think it was developed by israeli special forces and adapted to fit into the swat/fbi/us special forces training programs.
Check out http://www.TheDefensiveEdge.com taught by a local SWAT instuctor. Has his own line of ar’s featured in SWAT mag. and has lots of famous guest instructors. Classes can get spendy but are well worth the money. He has a great Concealed carry class too.
