Battlefront tells a bit about the upcoming Tour of Duty Vietnam War minis game in this Design Diary post.
From the post:
Four years ago I knew about as much about the Vietnam War as the next wargamer (so a bit more than the average population, but not much more). Tour Of Duty, Battlefront’s latest project, is my third visit to this fascinating war, and signals an escalation in both the status of Vietnam in Flames Of War and in the war itself. What started out as a minor side project has now become a core part of Battlefront’s range with a wide variety of forces awaiting you on the field of battle.
