The is the joint service military unit mandated to ensure the immediate security of the President of the Bolivarian Republic of Venezuela and his First Family and for the performance of public duties in the most important places in the country. The most distant antecedents of the Presidential Honor Guard go back to the "Hussars Troop" of Bolivar, of the Venezuelan War of Independence and of the larger Spanish American wars of independence, raised in June 1815 and part of a more bigger guards brigade targeted for the immediate security of the Liberator, and the early 20th century 1st Cavalry Regiment "Ambrosio Plaza" that until the 1950s, albeit reduced to squadron size, provided the ceremonial security of the President and was modeled on the Prussian practices of the late 19th century. The Presidential Honor Guard Brigade is composed today by the personnel from both the five service components of the National Armed Forces and the civil security services, and is commanded by a brigadier general or colonel or equivalent. At the moment, it is a unit of Brigade size. The Brigade provides the honor guard to the President in State Arrival Ceremonies at the Miraflores Palace and to the President in every activity held in the grounds and at the Tomb of the Unknown Soldier in Carabobo Field, Valencia Municipality, Carabobo, in honor of its participation in one of the final two battles of the Venezuelan War of Independence, the Battle of Carabobo on 24 June 1821, fought at the very grounds where the tomb is located, where a Guard Mounting ceremony is held daily in the midday hours. And from 2013 onward the Brigade is also charged with mounting the guard at the tomb of the late President Hugo Chávez at Fort Montana in Caracas plus in Bolivar's renovated mausoleum in the National Pantheon of Venezuela complex, also in Caracas, with guard mounting duties done daily, with all of them open to the public.
