"Panache?"
"Yes, it means 'Flamboyance'."
"I know what it means."
"Really? I had to look it up."

As is often the case, someone suggested I do more work. This is never one of my favourite things, but I thought as I had nothing better to do I might as well. The work in question is this glossary. In a continuing attempt to fill this site full of useful information (using the approach of posting enough stuff that some of it must be useful), I've grabbed what existing information I could find and attempted to increase and expand on it. The results are what you see below.

As always, if you think of any terms you'd like added, or find any errors, then drop me a mail.

Ten rules of a gunfight

  • 1. Bring a gun. Preferably, bring at least two.
  • 2. Anything worth shooting is worth shooting twice.
  • 3. Only hits count.
  • 4. If your shooting stance is good you 're probably not moving fast enough or using cover correctly.
  • 5. Keep shooting until the threat no longer exists; then stay sharp until somebody with a badge tells you to freeze.
  • 6. If you can choose what to bring to a gun fight, bring a long gun and a friend.
  • 7. In ten years nobody will remember the details of calibre, stance, or tactics. They will only remember who lived.
  • 8. If you are not shooting you should be reloading or running.
  • 9. Accuracy is relative: most combat shooting standards will be more dependant on "pucker factor" than the inherent accuracy of the gun.
  • 10. Someday someone may kill you with your own gun, but they should have to beat you to death with it because it is empty.
