The Seargeant-at-Arms is the ceremonial officer tasked with security duties for the Senate of Centralia.

Unlike Parliament Hall, which is guarded by the special Parliamentary Unit of the CentraliaHonorGuard, security for the Senate is provided solely by the Sergeant-at-Arms...a disheveled man in an ill-fitting security guard uniform, who mostly sits at his desk in the corner and plays on a clunky old laptop during Senate proceedings.
