I'm starting to get the basics, but some of the nuances elude me. For example, sometimes it's absolutely vital that posture will do what I think it will do, but I seem to get it wrong a lot.
Let's say you have two British forces--A and B--in Manhattan. Force A is set to Defensive. Force B is set to Offensive. Now a rebel force moves into Manhattan with posture on Defensive. The rebels will fight British Force B, to be sure, but will they also fight British Force A? Will A and B fight the rebels together or separately? And finally would anything change in this scenario if the rebels brought their force into Manhattan set to Defensive posture instead of Offensive?
