I've searched for hours to find a way of getting my units to the highest rank in Napoleon: Total War. I found a lot of tables showing the numbers when a unit gets a new rank, but is there also a way of getting to these ranks. So far i've only reached rank 6 in the campaign, this doesn't last long because of the replenishment. Also if you fight numerous battles with them they stay around rank 2/3. So my question is: Is there any way of obtaining a higher rank on the campaign?
Thanks for your effort,
