Since the image is as good as I could get... I have transcribed it below:

You've heard of the air forceand the Marines and Paratroops

But think as hard as you can

Though you've heard of the Army

And of other groups,

Have you heard of the Amphibious Man?

The Amphibious Man is a real rugged sort

But unlike the Fleet

He has no home port

Goes where he's needed

Does what he can

This poor Orphan sailor

the Amphibious Man

You might be a battleship sailor

From a cruiser or off a tin can

Maybe fresh out of Boot training

Or perhaps a second cruise man

The pick the man at random

How else could the provide?

A few might choose the duty --

But they are usually Shanghaied.

You've heard plenty of the Navy

Of ships, both for and aft,

But we'll bet a pretty penny,

You've heard least of the landing craft

And they've got to have the LCI's

to win this doggone war.

They're loaded from the transports,

In the middle of the night

Sail around to rendezvous,

Can't even show a light.

Find their way in Darkness

And land upon the shore,

Through bombs discharge their cargo

Then go right back out for more.

Bringing in the first wave

Doesn't end the job.

For the troops upon the beach

Can't live without this Gob

He brings in reinforcements

And everything they use

His Job is full of danger

But he never makes the news

For when the beach is taken

And the radio start to tell,

You'll hear of the Marines and Soldiers

And how they went though Hell.

You'll thrill to front page stories

Of their Heroic Job

But You'll never hear a word

of the poor Amphibious Gob!

And when this war is over,

And he back in Civvie life

How in Hell will he explain,

To his Kiddies and his wife?

They love he's in the Navy

But he's the subject of a Gyp

He's just an orphan sailor,

A Gob Without a ship!
