G4H-DuSH

The G4H-DuSH is a Human missile launcher used by the United Nations Space Command.

If the name of the weapon is read in L33t speak, it appears to say "Gah-Dush" which may come from the sound the rocket makes when it detonates.

Trivia

 * This was first seen in The Art of Halo 3, though it was cut from the retail version of Halo 3.
