Events During Season 1 - Vector Edit
Butcher, Smith, and Jones hijack a M15 ARV. At the same time, Strike-team Vector capture a Pelican dropship. Smith accidentally broadcasts their plan over the UNSC's radio. Vector was onboard the Pelican at the time. After being chased by Warthogs and Scorpions, Orion crashes the M15 and is evacuated by the Colonel. They return to Firebase Orion, a replacement for their recently destroyed base. Vector is shot down by UNSC interceptors. Orion is then tasked with rescuing the survivors. Upon coming back to the base with all of Vector, Rio joins Orion.
