Worms and other weaklings in purported service of the Great Lord, be warned: the actions of horse stabbing and ambushing will no longer be tolerated. The Dark Lord's most loyal servants will henceforth terminate with extreme prejudice any juvenile slime seen to disobey this mandate. There will be no lenity.
You are incapable of grasping the proper tactical criterion by which a mounted horse may be killed therefore you will not be permitted to do so. The Great Lord's most loyal will be forced to make an example of horse stabbers and will destroy any putrid worm who undertakes to ambush.
Old trollocs who carry badges and insignia other than Ko'bal, yet attempt the arts of stealth and silent death, you will be presumed to possess sufficient intelligence only to stab mounted horses when absolutely necessary for your survival, and to refrain from preparing ambushes. If you in fact lack such intelligence or restraint, we leave disciplinary action to your masters and to the Dark Lord's generals.
Written in blood,
Puny the Great Havoc
Krul the Master Havoc
UPDATE 27/11/16: This mandate is rescinded.
