I thought some of these were great...
* Bring a gun. Preferably, bring at least two guns. Bring all of your friends who have guns.
* Anything worth shooting is worth shooting twice. Ammo is cheap. Life is expensive.
* Only hits count. A close miss is still a miss.
* If your shooting stance is good, you're probably not moving fast enough nor using cover correctly.
* Move away from your attacker. Distance is your friend. (Lateral and diagonal movements are preferred.)
* If you can choose what to bring to a gunfight, bring a long gun and a friend with a long gun.
* In ten years nobody will remember the details of caliber, stance, or tactics. They will only remember who lived.
* If you are not shooting, you should be communicating, reloading, and running.
* Accuracy is relative: most combat shooting standards will be more dependent on "pucker factor" than the inherent accuracy of the gun.
* Use a gun that works EVERY TIME.
* Someday someone may kill you with your own gun, but they should have to beat you to death with it because it is empty.
* Always cheat = always win. The only unfair fight is the one you lose.
* Have a plan.
* Have a back-up plan, because the first one won't work.
* Use cover and concealment as much as possible.
* Flank your adversary when possible. Protect yours.
* Don't drop your guard.
* Always tactically reload and threat scan 360 degrees.
* Watch their hands. Hands kill. (In God we trust. Everyone else, keep your hands where I can see them).
* Decide to be AGGRESSIVE enough, QUICKLY enough.
* The faster you finish the fight, the less shot up you will get.
* Be polite. Be professional. But, have a plan to kill everyone you meet.
* Be courteous to everyone, friendly to no one.
* Do not attend a gunfight with a handgun, the caliber of which does not start with a "4".
