Rising Storm 2: Vietnam announced that they are adding ANZAC forces into the game, which made ne realize I know absolutely next to nothing on Vietnam outside of a basic understanding of US involvement.
So what did the ANZACs contribute? Why did they decide to contribute towards the war? What battles/operations were they engaged? What about forces of other nations?
It's an old post, but I've previously answered a question on "how did Australian Counterinsurgency tactics and strategies differ from those employed by the US in Vietnam?" which might interest you.
