During the war with the Trade Federation Army, the Bargos were recruited for the use of the Gungan Grand Army to haul the cavalry of Kaadus and the infantry. Each bargo was able to accommodate a full army unit comprised of 12 Kaadus and riders, 12 spearmen and 6 booma strikesmen. The top side was also used to haul the booma armaments by strapping them to the chains on the deck.
