My biggest gripe is no period flavor. So if you are looking to game out WE WERE SOLDIERS, pass on this one. You don't get a sense this is Nam. The game lacks detail, basically you have infantry platoons and leader counters. Mortars and Machine guns are factored into heavy weapons units. At this scale they should be shown as squads or sections. Their placement was often critical. The leaders are all the same, and as anyone who has ever served knows, all butter bars, second lieutenants, are not created equal. Same complaint with air strikes, very bland, a Sandy, Sky-raider could loiter for ever while a jet Phantom had to get in and out quickly. Finally the key to air mobile operations the helicopters are way to abstract, the landing zones are always, available and open. You wish...
On the positive side the map looks good and the variant cards add a nice touch. There are several miniature rules sets that do this battle better and more economically.
