In military parlance getting off the X is a term for moving while returning fire. As of late it means many different things but fundamentally it means remove yourself from danger. I have written in the past about the psychology of the criminal element in our society and how they take advantage of the “average” citizen, more importantly we as preppers need to learn how to keep the bad guys at bay during a SHTF scenaio. Believe me when I say I am no expert in psychology but I am trying to learn as much as I can.
I ran across this article explaining and talking about this very subject and the author is more articulate than I on this subject, so if your interested take a read. You will have to scroll down the page and find the entry From the Archives ~ Standing on the X
Give it a read, you might learn something.
