Based on this widely circulated graphic of ground formation vehicles, I've created an index for forum.
I couldn't find images of some vehicles. If you have relevant links, please DM or reply to me within an hour (edit time limit). I'll make updates accordingly. Thanks!
Note: This diagram was produced no later than August 21st and does not reflect the final rehearsal lineup from August 23rd, so discrepancies with the actual parade are likely.
