What to the letters next to the units mean, are they informative or not? For example I have an infantry unit on its own and clicking it shows "9th Infantry Batallion CG9" what does the CG9 mean? Other stacks of units have similar letters e.g. a multi unit type stack is CG1, is it the order they were constructed? Opposition units seem to have a different prefix e.g. CP3 or R2 etc.
Is it meaningless or can it be used to understand enemy units etc?
