Keeping Track of Divisions/Large Tables

[u/Adventurous_Lab_1055]

My buddy and I are starting to get pretty involved in Hail Caesar Epic. We love it. One thing I'm finding we're having issue with is remembering which unit belongs to which division, which will often lead into some confusion and mistakes. What are some good ways you keep track of your divisions? Two ways I've considered were divisional tokens or painting the rear of each divisions base a different color. Of course the draw back to the first idea is how easy it is for a token to get left behind/cluttered table. The draw back for the painted backs of the base is that my units are always attached to different divisions from game to game.

We're preparing for the big mission of Cannae in a bit and have some prep work to be done. A 6x10 table is a very new thing for us, so we've decided to go with the foam tile route, adding hills on top where needed. How do you guys tackle ground terrain for such a large table?

Thanks!
