The Senate Guards were police officers belonging to the Coruscant Security Force during the time known as the Cold War. Their responsibility was to safeguard the Galactic Republic's Senate Building, located on the capital planet of Coruscant. This responsibility was shared with members of the Republic Military who were designated as Senate Security Officers and assigned to the Senate Building.
During the Cold War period, the Coruscant Security Force (CSF) Senate Guards, who were police officers, were tasked with the protection of the Galactic Republic's Senate Building situated on the capital planet of Coruscant. The Republic Military's Senate Security Officers (SSO) also had jurisdiction over the Senate Building's security.
Some officers were present during a Senate Defense Subcommittee inquiry concerning the events surrounding the defection of Havoc Squad.
Additionally, they attended a formal ceremony to congratulate the Jedi Consular known as Barsen'thor.
Eventually, both the CSF senate guards and the Senate Security Officers were replaced by the more structured, and independent, Senate Guard organization.
