Born in Tumeremo, Bolívar state in Venezuela in 1925 he was orphaned at a young age and left to do a lot of the upbringing of his younger siblings Leopoldo, Ines Matilde, Antonio, Jose Francisco and Guillermo.
General Sucre went on to serve as a part of the United Nations's peacemaking forces (the famous Blue Helmets) in India in the 1960s during conflicts with Pakistan.
General Sucre's military career reached a high point when President Caldera named him Jefe de la Casa Militar (Chief of the Military House) which placed General Sucre at the head of all presidential security needs and procedures.
As Carlos Andrés Pérez, a member of Caldera's COPEI's main rival, Accion Democratica, took the office of President, he replaced Sucre Figarella with Manuel Bereciartu.
After achieving the highest office in his career, General Sucre decided to retire soon after his replacement was put in place.
