Talking about “Grey man” first though... Grey man is a multifaceted tactic that must observe everything - including the way that you walk and your body language.
If you meet with someone in town and your pockets are empty, your tells can easily announce that you have dropped your bag just outside of town and it’s full of goodies.
Stand in front of the mirror and make yourself look REALLY sick and degraded. Convince yourself that there is nothing left. Trick yourself into being that man. Cry when you see a gun. Act, act, act.
A gun carrier who is experienced will NEVER carry himself the way that a begging, worthless pauper would. You know that at your hip you have the answer to any question. This is your tell.
I’m playing around with the idea of making my wife a “Phantom”. Where she gets the gilly suit, she gets the good rifle and she basically follows my limping, un-armed walking corpse along the tree line. That way I can trust her to take out issues without being seen.
But to date, I’m taking a housewife and training her to be a sniper. It’s very risky.
Especially if she doesn’t like you as much as you think she does. ;)
