Recently re-certified in use of force/ground-fighting/knife defense/violent subject arrest/tactical handcuffing.
3 days of takedowns, throws, hard parries, wrist-locks and come-alongs...
Sore, and pleased that the instructor used me to help teach the class/coach the other participants.
Any RLSH/X-ALT would be well-served to take similar courses, such as PPCT/SPEAR/LOCKUP..
every system has its own way of doing things, and its own things it brings to the toolbox. Great stuff.
Had one guy get smart and try to bob mid-way through a 1/2 speed demonstration of an attack.... He caught a brachial stun and went down like a puppet without strings...
He was fine, just stunned. Good times.
