The Enemy Let Slip[]
At the perimeter of the base, Sergeant Major Trey Callum radioed to Princess that the Imperials were sending in some funny looking land transports, that they looked like camel droids, and they had lots of guns. R2 declared he wanted one, he wanted one so bad. Princess ordered the Rebels to destroy them all.
