Army for the Republic of Vietnam; they're often reffered to due to the fact Southern Vietnamese Army (SVA). They certainly were battling against the Northern Vietnamese. Republic army of south vietnam during the vietnam war.. (VIETNAMESE HISTORY) Army of the "Republic of Vietnam"; company produced, funded, equipped, because of the US government; mostly conscripts without motivation to eliminate patriotic countrymen within the country side (that will be exactly what the "Viet Cong" really had been). Excessively poor battling power; but fairly self-confident at staging the occasional coup d'etat.Collapsed entirely in early months of 1975. Mostly behaved as you would anticipate a group of brutally terrorized conscripts offering a regime they despised to act.
