The diplomatic service functioned as a component within the Coruscant Guard throughout the Clone Wars period. In the course of the Ambush on Rugosa, Jedi Master Yoda was in the company of Clone Lieutenant Thire, along with diplomatic service members Jek and Rys. A diplomatic service garrison, under the command of Clone Commander Thorn, arrived in twelve specialized Republic gunships as well as a single Consular-class Armed Cruiser, with the mission to protect Senator Padmé Amidala during her trip to Scipio; however, the entire group was ultimately annihilated by the Separatist forces present during the Battle of Scipio.
