I believe the original version from 1963 went something like this ---

The army has it khakis, the navy has it blues
but there's another uniform I'll introduce to you
the uniform is forest green, the finest in the land
Marine Marine Marine

The Corps was formed Nov 10th in 1775.
It formed the greatest group of men that's ever been alive
they wrote their page in history, with their blood spilled in every land
Marine Marine Marine

The Germans called us Devil Dogs, the name is just Marine
we are the finest fighting force the world has ever seen
and when you see the uniform you'll know just what I mean
Marine Marine Marine

And when we past a graveyard, we'll hold our heads up high
cause were the only fighting force with guts enough to die
and when we go to heaven to St. Peter we will tell
One Marine reporting sir, I spent my time in hell
Marine Marine Marine
