Acropolis ... Here is an example of the type of training course that could be useful. I am NOT necessarily recommending this particular course . That's because I don't know anyone who has been through it, and more importantly this course sounds like it is just a set of classroom briefings. That's no good . You need a training course that puts you into real simulated situations. It's possible I am wrong and this course does do simulations ... You would have to talk to them. Check out how the courses are conducted pretty carefully. If it' doesn't create a stressful situation and get your body moving in real simulations (with real simulated bad guys) then you are not getting value for money.
