957-A3

957-A3 was a Scorpion Tank built by the UNSC. It had what appeared to be an arrowhead painted on its left front tread cover.

In 2552, 957-A3 was assigned to the UNSC In Amber Clad. That year, during the First Battle of Earth, the tank was landed in downtown New Mombasa to fight the Scarab walker loose in the city. The tank was landed in front of the building being used by the 405th as a staging area, just in time for the Scarab to appear. The tank fired its main gun at the Scarab, to no avail. It was then destroyed, knocking off the tank's turret and killing its pilot.
