The diplomatic service was a unit of the Coruscant Guard during the Clone Wars. During a Mission to Rugosa, Jedi Master Yoda was accompanied by Clone Lieutenant CC-4477 "Thire," "Jek," and "Rys," members of diplomatic service. Clone Commander "Thorn" led a contingent of the diplomatic service to escort Senator Padmé Amidala to Scipio, although the entire detachment was later massacred by the Separatist garrison during the invasion of Scipio.
