Spartan killing machine

So here it stands again,
The spartan force
A wall of bronze and
Iron, phalanx of death
An iron-bladed forest
Of thousands spears
Rises high and solid
As a spike fence

Spartan fighting machine
Spartan killing machine
Spartan fighting machine
Spartan killing machine

The hearts I the enemies
Hammer in their breasts
Their blood is cold as ice,
Fear dwells in their eyes
As we accelerate
The pace of advance
Their shouts of threat and
Anger will be their last

Merciless warriors
Advance in battle line
A perfect war machine,
A brotherhood of arms
We will never retreat,
We'll sacrifice ourselves
For spartans it's not dying
But fleeing that is death
