You know, instead of tactically thumping your own tactical chests, you could have read his tactical post. He was being sarcastic about buying stuff to be tactical and asking what he can do to heighten his situational awareness, knowing full well....
*sigh*

You probably know about the Cooper Color Code,
white = ostrich
yellow = relaxed awareness
orange = specific possible threat
red = SHTF
Housecats have eyes on their butts and you can seldom sneak up on the little guys. They aren't paranoid, just alert.
Dogs on the other hand, go from white to red. They lounge around and you can walk up to them and kick them. Then they go nuts on you.
Basically you want to be in housecat mode.
I hear other things about playing games in traffic and on foot about trying to predict someone else's movement, but I find that for me, personally, it's counterproductive as I get fixated on one person or car. I just keep my head on a swivel casually.
As for being tactical, carry your junk on your offhand so you can access your weapons on the other.
Know the interview position and use it when dealing with people.
And don't forget to enjoy life. Tactical people, especially the 'tacticaller than thou' who post on the Internet, take themselves too seriously. We're all going to die one day and if you die tactically or not, it matters more that you brought truth, justice and joy into other people's lives, not being buried in the cemetary in the corner facing all the other dead people so you can keep an eye on them and react to a possible threat.
