PanzerBlitz: ACAV – Mechanized Warfare in Vietnam (1973)

This game does not portray the jungle war in the boonies, but the regular war on the coastal plains. It is here that the war reached its final stages, and will eventually be won or lost ... The terrain involved is quite similar to a few patches south of Hue...

This game looks a lot like PanzerBlitz, and the maps line up, and the factors inter-relate pretty well. That is intentional. PzB is a good game, and more than that a good game system ... You can call this a variant of PzB if you wish. Or, see if PanzerGrenadiers would have done better than American Rangers in Vietnam.
