TB-SB-1

TB-SB-1 was a Scorpion Tank built by the UNSC. It had a painting of a black lightning bolt surrounded by a white field on its front left tread cover.

The tank was assigned to the UNSC In Amber Clad in 2552. That year, when the ship was at Installation 05, the tank was brought to the Library in a Pelican while Commander Miranda Keyes and Sergeant Johnson searched for the Index. The Marines manning it were either killed or infected, as the tank was under the control of a Flood Combat Form by the time the Arbiter got to it. It was being used to attack Sentinel Majors and Enforcers by the downed factory within the Quarantine Zone.
