Hi, Sol - This Google Search will take you to a variety of versions. At Fort Leonard Wood, Missouri, we marched to:

I wanna be an Airborne Ranger
I wanna live a life of danger
I wanna go to Viet Nam
I wanna kill old Charlie Kong.

I tried to avoid that last line, mouthing the words without saying anything. I didn't like the rest of it much, either.

This version is pretty good:

2 Old Cronies lying in the bed
One rolled over to the other and said:
I want to be a paramedic
Use that funky anasthetic
Paramedic/Anaesthetic
I want to be a scuba diver
Jump right in that muddy water
Scuba diver/ muddy water
I want to be a mountain climber
Climb that mountain higher and higher
Mountain climber/ higher and higher
I want to be an airborne ranger
Live a life of guts and danger
Airborne Ranger/ guts and danger
I want to be in color guard
Live a life that's not so hard
Color guard/ not so hard

This one and lots of others here (click).
