These are settled Sea Peoples allies of the Trojans. Natural forces for Posideon.
I’ve already got some Museum Miniatures ox carts to produce smaller not-chariots like these Magister Militum miniatures. https://www.magistermilitum.com/sea9-ox-drawn-wagon.html Alas, these are true 15mm, so will look too small.
After all, you can never, ever have too many chariots on the go at any one time.
On that note, way back in April I backed the sort of pre-order kick starter for Battle Valors new chariot range for 4 mediums - and I received 8! Cannot argue with that! Essentially this is 2 different sized vehicles pulled by different mounts and crew per race.
They were posted in January and I got them exactly a month later, which is quick for transatlantic post these days. A big parcel, I paid an extra £39.32 VAT & £12 clearance fee. BUT, that's less than the cost of the extras I got for the kickstarter, so I'm still squids in. Hail Posideon!
