odd......”Run, Hide, Fight” doesn’t sound like a well thought out statement......
It's being taught in a lot of active shooter courses for corporate/govt./campus training where personal defense weapons are not allowed.
The idea is to run if you can, hide if you can't, and fight like hell if run and hide are not an option.
Run, hide, fight is what you are taught in concealed carry class.
That is the proper order of business whether armed or unarmed.
Though you could run toward the shooter shooting wildly if armed and waving your arms and shouting if unarmed.
