CQC and CQB, close quarters combat and close quarters battle, do exist. Used by the military. If you join the Army or Marines you will learn some form of either or both. I learned some in the Navy working security forces and later learned some more when I joined the Army. It's not some big secret, it's just learning tactics for firefights.
