During the early rebellion against the Galactic Empire, a document titled Readiness Report: Surface Vehicles was created by General Pitt Onoran of the Rebel Alliance Special Forces for the Rebel Alliance. Lieutenant Taidu Sefla also provided commentary within the report, which detailed several rebel vehicles employed by the Alliance. This document was given to Mon Mothma, a key leader in the rebellion, and it was subsequently discovered in 34 ABY as part of The Rebel Files, a compilation of Alliance documents.
