Sniper attacks in collapse and mass shootings today in peaceful times have a lot of common things, but some facts are different.

I will concentrate here on some advice concerning sniper attacks when SHTF since I have seen and experienced more than a few of those.

What are the reasons for sniper attacks?
I know you all seen movies or read the books about sniper attacks that are been made with careful planning and surgical precision from a great distance, by highly professional personnel. You might see that when the world goes to s**t, but most probably you won't ( unless you are in the military profession).
