I really like what I am seeing with the unit commands but where are the cornicines (musicians) they were important? I know things are still a bit early but its a legitimate question. I never fully understood why CA has piecemealed us unit commands throughout the series with the exception of ETW and even that was spotty when it came to cavalry units. Unit commands should be fairly straight forward for this period Officer, Standard-bearer, and Musician. In this period the cornicen was extremely important and would always be next to the centurion to signal orders to the legions.
It would be pretty cool to issue an order to a unit and see the centurion bark out the order followed by a signal from the cornicen. We are ready for this CA! Also I noticed there was an eagle standard in the background of this screen shot, I imagine it's probably the first cohort but they should a have signifer as well. Deck these units out with unit commands CA it only makes them look better, could you imagine the 1st cohort with the following unit command Officer, Eagle Standard-bearer, Signifer Standard-bearer, and Cornicen! and give cavalry units some lovin too they deserve full unit commands as well and it's historical see trajans column.
