Also, if anyone is curious, this is the current state of play in Vietnam on turn 12:
NVA has made some inroads, taking out 1 US base
Both NVA and VC seem to be massing for an attack on Saigon, but the VC has been hard hit by US actions, losing 3 bases.
US recently wiped out a massive NVA invasion in Hue, but the air strikes there have garnered opposition to the US presence.
ARVN has effectively maintained enough control and siphoned off enough aid to private coffers to be very close to winning.
Bodycount (not sure how many people are represented per token, or how many of them are considered dead when a token is removed):
US: 1 base, 2 troops, 1 irregular
Vietnamese: 3 bases, 17 troops, 4 police, 11 guerrillas
