Ambush

Mission, to hunt the evil down
Creeping in without a sound
Prepare for silent attack
There will be no turning back
Penetrate, Isolate, Decimate, Ambush
Silent supremacy
Stalking picking up the trail
Never retreat and never fail
Got the target move in for the kill
Take him out fire at will
Campaign over, battle won
Supremacy second to none
Vanished, gone without a trace
Assassins for the human race
