At the time, GDI had discovered a fortified Brotherhood position that was defended by Obelisks of Light leading to an assault on the enemy position. However, a powerful dust storm engufled the region which led to a number of Orca's crash landing in the battlefield. The pilots were stranded and were trapped in a situation where they could either die by the sand storm or, it if abated, die at the hands of a Obelisk of Light which would gain a targeting sight on the pilot's position. As the battle raged, GDI commanders decided to field test their new AT-414 Refractor tanks.
