The Taloos group, consisted of Container Transports from Xizor Transport Systems, and their purpose was to move materials.
After the Battle of Hoth, the container transports, both of them, were examined by staff at Outpost D-34, specifically Maarek Stele, who discovered they were transporting equipment. This examination happened at the same time as a Rebel assault on the platform, but because the transports seemed harmless, they were allowed to proceed to their destination.
