If you have ever served in a military branch that dominantly conducts ground warfare, or have served in the smaller elements of the other two branches that don’t, then you already know the difference between cover and concealment.  (LEOs, you get a pass on this one, as well.)  A lotta people out there do not know the difference.  No biggie.

Until it IS a biggie, and you’re trying not to get shot or blown up.

As probably most of America has heard or learned at this point, when some sort of kinetically derived emergency happens–active shooters, explosions, etc.–you are supposed to do one, two, or all, of three things:

1)  Run.
2)  Hide.
3)  Fight.

For this little ditty, we’re assuming you are out on the town, and not in any status or disposition to engage; you are focused *away* from the pops and bangs, not *toward* them.  (That establishes Course of Action 1:  Run.)

Run.  Remove yourself immediately, if not sooner, from your current location to a location that is as far away from whatever is going down wherever the shit is going down, as possible.  If you can keep moving, do so.  (We should all know by now what my policy on a safe finish is, right?  You’re not safe until you are back home and no one is coming after you.)

We’ll assume you can’t get as far as you want to get, and have to shift gears to Course of Action 2:  Hide.  COAs 1 and 2 both adhere to what Mr. Miagi referred to as “the best defence”:  No be there.  But in the event that you can’t “no be there,” you can do your damnedest to be out of sight (which is effectively the same as not being there, if you’re good enough).

I, personally/unfortunately, have got a pretty damn good running record of performing all three of these COAs.  And although the root of my need to do any of them is completely different than those listed here–as well as self-inflicted–dynamically there is no difference in how you would proceed, in any event.
