I'm told you do a few hours' worth of unarmed combat on the mats in CS95 during Recruit Training, basically it focuses on "how to bring a man down".
The Commando Display Team undergo a fair bit of training in this area (2 or more months' worth) and last time I saw them, it shows, as they are brilliant to watch. They use a great deal of humour in their displays if you watch closely, they always seem to end up black & blue too as they don't always pull their punches.
My advice, if you ever get the opportunity to watch a Commando Display Team in action, make every effort to go and see them.
