If you'll carefully note, we made no effort to hide that this document came from RPGChat.
If you'll note ever more carefully, you'll notice RPGateway doesn't have an official set of rules regarding fighting, RP, or anything of the sort.
Now, if you'll try very hard, you may even notice that this is posted in the Library. What can you find in a Library? Reference materials. Yes, sorry to burst your theory, but this is just a reference piece, provided for those who like the idea of this style of combat.
Better luck next time.
STAVE: Commala-come-ki,
There's a time to live and one to die.
With your back against the final wall
Ya gotta let the bullets fly.
RESPONSE: Commala-come-ki!
Let the bullets fly!
Don't 'ee mourn for me, my lads
When it comes my day to die.
