SCARS training... The best offensive hand combat course I ever took. No screwing around... Forget about “defensive” techniques when fighting. Permanently disable or kill your adversary... Your choice, no regrets.
Excellent, thought it might be something like that. SCARS is something I’ve heard of through some buddies ex spec ops.
Also for firearms, Massad Ayoub’s book “Armed and Alive” and “The Truth About Self Protection”
are very useful. He runs the Lethal Force Institute.
