Haitian honour guard duties are performed by the General Security Unit of the National Palace of the Haitian National Police (L'Unité de Sécurité Générale du Palais National, USGPN) which is a major specialized unit of the PNH. It has, since 1997, mainly ensured security at the Palais National and the security of the President of Haiti. The USGPN works with the Presidential Security Unit (Unité de sécurité présidentielle, USP) to protect the president, as well as intervene when a crime takes place and or assist police officers in their duties, outside of the USGPN's ceremonial ones. Funeral honours, state visits, and military parades are some of the many ceremonies that the USGPN takes in.
