to unify the national police services following the example of Chile. It reverted to its former name later that year at the order of President Luis Miguel Sánchez Cerro. The regiment underwent a new reorganization in 1932, with a new motto: "Honor, Loyalty, Discipline". It remained the presidential guard until shortly after the assassination of President Sánchez Cerro on 30 April 1933. The reorganized Regiment comprised a regimental headquarters unit, service battalion, and two battalions of 3 rifle companies each, plus a machine gun platoon, the regimental band and drum corps. The role of the Guard was expanded in 1935, to include border patrol, prison security, protection of public and private places of national importance, and general maintenance of peace, public order and national security, in addition to fighting alongside the armed forces in times of war. With the expansion of its role, the Guard left palace duties in 1940. Responsibility for the security of the President and Government Palace was taken over in that year by the Palace Machine Gun Detachment of the Civil Guard (Destacamento de Ametralladoras de Palacio). From 1944 to 1969, it continued in that role as the 23rd Command of the Civil Guard - Palace Machine Guns (23ª Comandancia de la Guardia Civil – Ametralladoras de Palacio). It was reorganized into a police unit in 1969, and was succeeded by the Assault Battalion of the 22nd Command of the Civil Guard (22ª Comandancia de la Guardia Civil del Perú - Batallón de Asalto). In 1987, protection of Presidential security was assumed by the 501st Military Police Battalion of the Peruvian Army (Batallón de Policía Militar Nº 501). Today the Government Palace Guard performs largely ceremonial public duties for its Commander in Chief, the President, and his family on behalf of the Armed Forces and the National Police of Peru. Palace security is assured by the personnel of the Presidential Security Division, the State Security Directorate and the Civil Disturbance Directorate of the National Police. Horse Guard The "Mariscal Domingo Nieto" Cavalry Regiment Escort (Regimiento de Caballería "Mariscal Nieto" Escolta del Presidente de la República del Perú) is the Horse Guard of the Government Palace. Other than the period from 1987 to 2012, it has served in that role since it was first raised in 1904. Modeled on the French dragoon regiments of the late 19th to early 20th centuries, this cavalry regiment was formed on
