Jungle

The Air Force or Navy might fly the space ships, but it was the Army men of the Astro Ranger Force that would do the ground fighting on other planets.

Here in the South American jungles they trained for that day, wearing their distictive golden uniforms.

You never know what kind of weapon you will need to survive and so they practice with spears and wearing space helmets in the jungles of Earth.

The only men allowed outside the compound, facing unknown dangers, just at they will on Mars, the Moon or Venus.

Even so they don't stray far and are under observation of the outposts.
