Syria The First Field Army was a designation used during the period of the United Arab Republic. It was based in Syria.Central Intelligence Agency, 'Central Intelligence Bulletin,' 11 October 1958, accessed at https://www.cia.gov/readingroom/docs/CENTRAL%20INTELLIGENCE%20BULL%5B15777415%5D.pdf, October 2021. During the period of the United Arab Republic, army forces based in Syria was designated the First, and the other army in Egypt the Second (and possibly Third). By 1973 any use of the 'First' designation in Syria had ended, but this did not stop erroneous Western press reporting that forces of the Central Military Region around Cairo were designated the First Army.Trevor N.
