How Realistic Is the Fremen Sand Attack in Dune?

[Whitestar]

In Sci-Fi Channel's "Dune", there is a scene in which the Fremen attack Gurney Halleck and his men in a really cool fashion: They pop up from the sand and attack them.

Here is a clip of that scene:

I would imagine that for this to work, an oxygen mask would be required, at the very least.

My question is, how realistic is this type of attack? That is, how could such an attack tactic work in real life such as popping up from the sand? Would it require the aid of some kind of technology or is this pure fantasy?

Not realistic at all. The movie is ~ from the same years when it was about ninjas popping up from everywhere: from the ground, from the woods, from thin air. It's the same.

Some camouflage might be possible, but for that you better reference the Lord of the Rings movie instead:
