This is a search and destroy and rice harvest security operation across Binh Tuy Province, as well as a conterinsurgency operation designed to break the hold of the Viet Cong over the area.
Historically there were no engagements.
The objectives are farms that the US forces have to convert as well as destroying the enemy.
The US airpower can only be used when spotted by the US recce unit (within 3 hexes of them but not in jungle) so you cant sit there attacking the Viet Cong stacks regardless of sightings/locations etc.
It is also the intention that print and play players use hidden movement for the Viet Cong player. No specific rules, but either print out multiple maps or use pen/paper to plot locations etc. Also, US player must plot moves 3 turns ahead but can respond as required to spotted units. Hidden movement rules will expland on this when complete.
