The Entire American Military Operation in Vietnam vs. The Entire Population of Europe in 1340 A.D.

Scenario: Each side has every resource that had at their disposal. Military side only has access to who and what was ever physically present in Vietnam, however. So they are only allowed as much ammunition, vehicles, food, etc. that was ever in Vietnam, not what was in the United States or elsewhere.

Win condition: Total War to the last man standing.

Location: European continent circa 1340 A.D.
