In previous TW games it's been possible to remove the banners over the units either by changing the preferences in-game or by editing the preferences file.
I've checked in-game and it does not seem possible to be done there.
Has anyone found this in the preferences file? At the moment one of the joys of using Windows 10 is that I can't change the permissions to even edit the AppData folder in the 'virtual store' (there are times I can't even create a new folder unless I run some fixes - but then I get a Windows update and it messes it up again).
Edited: The account I use on my PC has admin rights.
