Let's start by defining a militia:
Dictionary.com offers a very concise definition: a body of citizen soldiers as distinguished from professional soldiers.
A simple google search for Militia gives this: a military force that is raised from the civil population to supplement a regular army in an emergency.
Both agree that a militia is a civilian force separate and distinct from a professional army.
How do we define army?
A google search: the branch of a nation's armed services that conducts military operations on land.
Dictionary.com: the military forces of a nation, exclusive of the navy and in some countries the air force.
Both agree that an army is the military arm of a government that focuses on land warfare.
Professionals who are equipped and trained by a body representing itself as a government.
While we're on dictionary.com, what does it say about the Viet Cong?
a Communist-led army and guerrilla force in South Vietnam that fought its government and was supported by North Vietnam.
They define them as an army? Why would they choose that instead of militia?
Let's go find out more: cross referencing across sources like BBC, the Museum of the United States Army, and other sources....
Viet Cong was a derisive term applied to militias in the 40s during the uprising against the French.
Well, that's interesting. Being referred to as a militia. Seems like a wrap, right? The dictionary AND whistlelock are wrong.
I wonder what happens if we keep reading?
Oh, in 1950, after the treaties are signed and North Vietnam and South Vietnam become official countries. But what about those militias? Well,they become the National Liberation Front.
A professional army trained and equipped by North Vietnam to overthrow the US backed South Vietnam government. They had guerilla and 'regular' units.
They weren't a bunch of civilians with guns. They were professional soldiers.
When did the US enter the Vietnam conflict? 1965.
By the time we enter the conflict, the Viet Cong was a professional army under the direction of North Vietnam (an actual country). A few years after our entry, they are the military of the Provisional Revolutionary Government (PRG).
