The hot wind blowing,
jagged lines across the sand.
The crumbling buildings,
in our minds are all that stand.
Just like the buffalo
I'm following a herd.
We try to justify
all the things that have occurred
I know what I've been told
The wishes of the people can't be controlled.
I know what I've been told
The wishes of the people can't be controlled.
Heat of the desert,
dust settles on my face.
Without a compass
the soldier knows no disgrace.
Out of the ashes
the eagle rises still.
Freedom is calling
to all men who bend their will.
Here I am
dirty and faceless,
waiting to heed your instruction
On my own
invisible warrior
I am a Wind of Destruction
We fight for justice
in a forgotten place.
Fulfill our duty
then vanish without a trace
Don't need a medal
for all the men we've killed.
Freedom is calling
to all men who bend their will.
