So the regular Knife Hand wasn't enough for you eh? It wasn't intimidating enough. It wasn't powerful enough. You need more. You need to be feared, because to be feared is to be respected.
I understand.
I have just the thing for you but I must warn you, its instructive power is great. The mere presence of it has caused full bird Colonels to drop into the front leaning rest. It's power is so great that it can even teach LT's how to do land nav. I once saw a Sergeant Major use it to command his grass to grow just so that he could make an E-3 mow it.
So, be careful. You have been warned.
