I had originally decided to simply add a flag to one of the command tanks, for the sake of realism, but quickly remembered that I was painting plastic army men. The "extra armor" is of my own design, each of the turret hooks has been replaced by actual loops and there is spacing in the tracks. I used a sponson HB for the hull mount.
Rating: - There is a small mould line on the hull heavy bolter -- as this is the army I game with I didn't worry about it much. Thanks for the feedback - once I (finally) learn to take better photos I'll get them online... including a full army shot.
