Regional commands
How the command structure work
- The Republic of Vietnam Armed Forces consisted of four military corps (Quân đoàn) I,II,III,IV responsible for the administration and control of four military zones of the Republic of Vietnam. Each military zone operates specifically within provinces/regions. This system is somehow related and works almost exactly the same as the ancient Roman legionary system, in which each legionary was also responsible for administering and controlling a specific province of the Roman Empire. By any mean necessary the word "Quân đoàn" means "Legionary" in Vietnamese, which would explain why the Republic of Vietnam Armed Forces operate almost exactly the same as the ancient Roman legionaries. While these details are not crucial or important in any way, it is still quite fascinating to know about them.
