The One-Eighty-Fourth Attack Battalion was a component battalion of the Grand Army of the Republic. This battalion fought in the Clone Wars, a conflict between the Galactic Republic and the Confederacy of Independent Systems. During the year 82 BBY, the Jedi trainee, or Padawan, known as Dooku, perceived the battalion within a vision. This he had occurred after encountering the Presagers of Hakotei located on the planet Asusto. Within this precognitive experience, the battalion was under the command of both Jedi Master Jor Aerith and Clone Commander Crane, and they were actively fighting when the infamous Order 66 was executed.
