How is line of sight traced in the game? Is it a ray trace, or something more abstract?
I don't know how sophisticated it is, but in Grognard mode the 3D viewpoint is locked to the officer you're commanding. This was not implemented in the current demo, but will be in the next one. The F6 view gives you just enough visibility to give simple orders on the 3D view, same as it does now. Try the F6 view from a corps commander and tell me what you think.
Two people playing together, each commanding one side, will only see what the CinC can see with the F6 view. If two people are on one side, one will have a corps commander and can only see what that corps commander can see from his F6 view. I'm not sure exactly how it works if each player commands more than one corps on a side, or even if that's possible.
