What are the units on the game banner?

[Enderspoons]

I've played Supreme Commander for a very, very long time and know its unit selection inside and out. However, on the very banner that's displayed on the game's steam page, there are several Aeon units that I have no idea what they are.

Does anybody have any idea what they are, and if they do, can they point out which things are what?

Probably some unused assets? Old Promotional work? They look like modified units from several of the factions. ( If it's the same image i'm seeing. )

Colossus minigunners and Spider Bots with archer towers.

Yeah, just noticed the giant turtle cannon walkers myself and had to do a doubletake.

I love in the intro how the Commander shoots down a plane!!

It's from a mod, Revamp Expansion Mod by Avitus

From, like originally? Or did Avitus model his 'mod' from the concept art's unused designs?
Weird to think a post-release 'mod' would be the inspiration for official art.
