Forced through a fine mesh screen

Futurama is awesome. Zapp is a ridiculous captain in their military. They're going to war on some distant planet. He preps the crew:

Men, you're lucky men. Soon you'll all be fighting for your planet. Many of you will be dying for your planet. A few of you will be forced through a fine mesh screen for your planet. They will be the luckiest of all.

Later on:

Zapp: It's a desolate, ugly little planet with absolutely no natural resources or strategic value. Questions?
Soldier #1: Why is this Godforsaken planet worth dying for?
Zapp: Don't ask me, you're the one who's going to be dying.
