Leave nobody standing

Civilians, soldiers
No need to differentiate
Bullets, grenades, bayonets
Thrust that blade into the pyre!
Torching the living
In a race to meet the tonne
But when there's this much killing
Well, who's really keeping track?
Leave nobody standing
Let them know the thrust of your blade
The fewer remaining
The less chance this campaign
Comes back to haunt us
Avoiding said problems
Best achieved by their deaths
Raped, killed and mutilated
Slaughtered in front of family and friends
For this man's pleasure
Is his victim's pain
And what's an invasion
If no one is slain?
For if we are diligent
And we clean up our 'mess'
Our unbridled savagery
Generates no regret
For if we are diligent
Cancel out our debts
Their truth becomes fable
Their story dies with them
For what is war
If not a means to settle a debt
A blanket under which you'll do as you will
Refining the hunt, perfecting the kill
