A Science Lance is a military unit tasked with the recovery and examination of enemy technology. Science Lances were dispatched to the Chi Ceti system in 2525 by the Prophet of Regret to study captured technology and equipment from the Damascus Testing Facility. Though all the Mjolnir Powered Assault Armor suits had already left with the Spartan-II's, they may have gleaned information from the rest of the facility, assuming it was not destroyed by the UNSC.
