I know they're rather obscure (and obsolete) nowadays, but they've been a minor fascination of mine for years.

Wouldn't normally ask, but given how there's already a couple of half-tracks in the game and those being another mostly absolute type of tracked vehicle, I'm curious. You just never hear about these things outside of museums, and it would be such a cool historical thing to get to actually see 'em in 3D.

Personal favorite, if it matters? The Renault UE Chenillette slash UE2. Just a sucker for how they look.
