Dust Giants

"Position compromised. Casualties unsustainable. Request heavy air. Request [Dust Giants]."
- Cryptarch translation of Sand Eater tactical chatter
Highly trained and heavily conditioned, Dust Giant soldiers seem to be recruited from veteran Sand Eater infantry. The Cabal order of battle positions them as a mobile reserve and shock force, rolled in to blunt major Vex offensives and reinforce crumbling lines.
