Thanks for the kind words and the questions.
(1) The darker terrain hexes are level 2 terrain, and the other hexes level 1.
(2) Yes, it's only Scenario 1 where the Confederates are under this restriction, and in Scenarios 2 and 3 they're able to bring them on later.
(3) Yes, you start the marker on the indicated space (the 8 space in the green band in this case) and you move the marker one space to the left (toward the yellow/red) with each activation.
Thanks for the quick reply! I’ll take some pictures and post a session report. Me and my friend are starting a bit of an ACW kick having played The Guns of Gettysburg last time, this time we’ll be playing a shorter more granular game on ACW (Next we might zoom out to the operational level view of Operation Shervport).
