A while ago, I was commissioned by a member of this forum to make a 3D-printable model of the Ariadna TAG RM-100. From what I understand, this TAG was never actually made into a miniature by Corvus Belli and was only featured in some printed media. Here's the single image available of it, and the only image I used as reference while modeling. Hope you folks like it!
Thank you! To be honest, I don't really know. I'm not very familiar with the game itself. There's a bit more info about this project here.
No, Ariadna has no units with that silhouette. Could use as a cool piece of terrain or it in another army if you like the design however.
