They're making a HUD that will be able to tell you at a glance some basic info on units/cities. I believe Frogboy said they're purposely staying away from banners, though.

in tactical battle screen will a unit of 4 / 8 / 20 or however soldiers be shown as 1 single soldier or will the whole unit be shown? if the later, i think it would also be cool if you got certain benefits when trooping soldiers (independent if you stack single soldiers together or built a unit from the start) bonus if you stack a unit of a certain amount of soldiers (maybe 12 for foot troops and 6 for cavallery or so), like they get a morale boost, and also a flag that represents the unity of their unit...think that would be cool for tactical battle and increase the "battle/army" feeling...also if you could maybe add a champion/sovereign to the unit which would further increase morale / fighting abilities...

okay...thats good, but still think squads/units should be represented together as a unit...like in mom or warhammer mark of chaos etc...
