The second half of the 20th century, was just as turbulent for the entire Venezuelan military, but it was projected into the future as a modern force for the coming years, though not yet cohesive. Already under the government of Major General Marcos Pérez Jiménez, who led the country as president and Commander in Chief from the early 1950s to 1958 (he was, under LTCOL Carlos Delgado Chalbaud and Germán Suárez Flamerich, the Minister of Defense) and the American influence (cultural, political and military), which started with the 1944 arrival of the first US military mission, became more prominent then in the entire history of the armed forces. So jealous of the Venezuelan Army, over the subsequent decades, the armed forces kept a precarious existing French influence, as a balance to the overwhelming American influence in the armed forces. Between the years 1945 and 1952, there was a major program of military equipment purchases almost monopolized by the United States (although other military material was acquired from other countries, mostly NATO countries) plus the military missions sent by that country, and later repeated again in the early years of the decade of the 1970s, albeit in a more balanced way by their countries of origin.
