Omega Signal functioned as a directive for all members of the Alliance to Restore the Republic's military to cease engagement with opposing forces and fall back. The authority to disseminate this evacuation order, which was uniquely coded, rested with Alliance personnel identified as Alliance Battle Staff. A specific instance of this code being used was during the Battle of Hoth, where it manifested as: "K-one-zero, all troops disengage."
Additionally, Omega Signal served as a command employed by on-the-ground small-unit commanders for the exact same objective. Commanders leading units like starfighter squadrons possessed the ability to utilize this command to mandate an instantaneous retreat of their forces, or to caution them about a potential ambush or the compromise of their concealed position.
