GSG-9 really are nothing more than an anti terror police unit. They are not allowed to leave Germany's borders or anything like that. There was some GSG-9 in Iraq protecting the German Ambassador but nothing else.
KSK is the military unit and is based off the SAS and recieved there training from the SAS.
