SPARTAN Group Omega

Spartan Group Omega appears in the trailer for Halo Wars. They're wearing what appears to be Mark IV MJOLNIR armor, although if you look carefully you can see the articulation points are lit up, and the armor looks less rounded than the normal Mark IV.They also appear to be armed with BR55 Battle Rifles or a similar variant.The barrel of the Battle Rifle is also slightly extended, and a little more blocky-looking. The identities of the team are unknown, although given the voice of what appears to be their squad leader, the Master Chief does not seem to be among them.

The name "Spartan Group Omega" is strange as the Spartan IIs often color code their squads (eg Red Team, Blue Team, and, albeit, there is only five of them noted to be visible in the snapshot, meaning they couldn't be a whole company. Bungie was probably looking for a way to incorporate the Spartans into their new game, so the "Spartan Group Omega" probably has little or no revelance to the actual spartan story and plot, unless the Spartan Group Omega is a squad of the SPARTAN-III Program, which is highly doubtful, because the entirety of the Spartan III's use squads, not groups, also unless Bungie decided that they would make this a fluke, like the SPARTAN-458 in Dead or Alive 4. Also, the SPARTAN-III would not have been trained at that time, and the spartan IIIs were probably just coming out of child hood 27 years before Halo Combat Evolved. Omega could be a group within a group, such as the classifications of Red Team in the battle for Reach. When split into smaller groups, Red Team ended up being Alpha Team, Beta Team, Gamma Team, and Delta Team.

Rumors

 * Gray Team may possibly be part of Spartan Group Omega before their disappearance in the novel's storyline.
 * This may take place twenty-seven years prior to the events of Halo when the Spartans IIs where 14 and on a diffent mission.
