The CR-20 Troop Carrier. Originally used by Corellian Security Forces, the Galactic Republic purchased surplus CR-20's roughly a month after the Battle of Geonosis. Used when the Acclamator Class assault cruiser was deemed unnescesary or not able to land. Holds approximately 40 Troopers, or 12 Speeder Bikes and their Pilots.
I tried to make this as acurate as possible, and to be purchase-able from the lego factory, but it wasn't possible to make it to be purchased.
