Thank you, Eagle. I appreciate you taking the time to reply to my post. I apologize, I should have worded my question a little differently so that it didn't ask for any specifics on training/methods and I'll keep that in mind in the future.
Thanks also for the suggestion of search terms. I admit, I hadn't thought to look under those specific terms, which is probably why I couldn't find anything online or anywhere about this subject.
The info you provided, however, was truly helpful and gave me something to think about and perhaps some other avenues that I can explore as well to figure this out.
I really do enjoy this site. It's fun, yes, but it's also really comforting to know that there are knowledgable individuals concerned with securing the rights and freedoms of people in our country and around the world. [Of course, there's a bit of hero-worship included there, too.

Take care and again, thanks for your time and attention,
JP
