Jesse, I hope you are talking about Commonwealth markings? I saw pictures of it at Thunder over Michigan!!!
You could do what I do, have magnetic signs made up and just choose whatever one you want to use for a event or display. Axholme signs in the UK makes awesome unit/tactical magnetic signs. Plus you can get the stencil ones to paint your S number, stars etc.
I would love to see 7th armoured division (red rats) 5th royal horse artillery.. Then when I come up north with my goodies they would match.

Or
4th armoured brigade (black rats) 4th royal horse artillery
Same as above, we do this too..
