030569

030569 was a Scorpion Tank built by the UNSC.

030569 was a Scorpion attached to Fire Team Zulu during the Battle of Instalation 04, during 2552. As the fire team's  Pelican crashed in the canyons close to Halo's Control Room, the tank detached from the Pelican and slid on the ice some 20 meters. It was discovered by the Master Chief who used it to fight his way through the canyons, destroying multiple Ghosts and Wraiths. However, the Chief and the Marines had to abandon the tank at a set of pipes where it was too narrow for the tank to continue.

The fate of the tank is unknown, but it seems it was captured by the Flood, using the training from human combat forms to control it, possibly attached back to the Pelican, as both had disappeared when the Master Chief returned when destroying the Phase Pulse Generators.

Trivia

 * This tank appears to be the only tank in Halo: Combat Evolved, as all multiplayer tanks are labeled alike.
 * The tank's serial number is an Easter Egg. See Birthdate on Tank.
