Because Frontline has Black Watch and French Royals/Marines, I am somewhat doubtful that JJ will go in the direction of Ticonderroga, but it has my vote.
Abatis, shallow trenches, log breatworks, sandbags -- easy on those diodrama buffs and perfect for glass curios.
For some reason, I am thinking the Indian Village will be soon, but that is just from reading these boards. Not fully sold on the idea of an Indian Camp. However, I will scream if there is a palisade wall around the village where the opening heights allows one to fire from the outside looking in as in the current palisade wall. If you have openings, the bottom of the opening height needs to be at least 6 if not 7 feet off the ground. I still cringe every time I look at the current palisade walls and the Blockhouse.
