Full FOW might be fun but how realistic is it, I think "Marker" is closer to reality, I know you guys will correct me if I'm wrong.
In all my reading and research, I have found that a CiC would have a pretty good idea of his enemies general dispositions. Not only does a CiC have scouting Cavalry, but he has intelligence gathered locally and spies. It would be a poor General who ventured into battle not knowing where even one of his enemies formations were approximately located, never mind a rough idea of strength. That's why I feel "Marker" is far more realistic.
Maybe there is an exception for an ambush, in a smaller scale engagement.
I mean, come on. Could you imagine Napoleon briefing his Corps Commanders.
" OK. Mes Generals, I think Wellington maybe somewhere in the region with a few of his chaps. I don't know where or even approximately how many and you all know me, I love going into battle blindfolded with the "Flower of France" to scatter around, in fact I'm famous for it. So, let's treat the field in front of us as a battleground and attack it, if you find any enemy there, we just might manage to kill them. Deploy your Corps in X, Y & Z, you'll have to work out the formations and strategy yourself based on whether your going to have a fight with a Hill or a Forest. Oh, and if you happen to see Wellington's chaps let me know and we'll figure something out".
