Them! and GIs

Vast numbers of Them pour from the nest.

But the men are here in large numbers too.

And some of them have...

A flamethrower!

 Their rifles, submachine guns, grenades and flamethrowers rule the day.

The men seem to have one a great victory this day.  But the Medicine Man waits, because the Indians know the desert and they know Them!

Them! and the GIs

Near the end of the great World War number Two, men are in the desert.

 Them attack.

 These men have seen war on an industrial scale.

 These men have fought in the Pacific and seen waves of humans attack.

These men have greater experience and fortitude than those men who came before.

Them!

 Time passes, and it's time for Them to return.

Men have been learning.

Men have been preparing.

Men are more at home in the desert.

Men are ready to do things they could not do before.

Them and Cowboys

 The cowboys fight to try and escape.

 They cowboys look for a chance to leave.

 They begin to make a break away from Them.

The cowboys managed to escape, but no one ever believed their unbelievable story.
