I assembled one of the Oathmark humans to see how it scaled up next to the GW/Citadel Empire soldiers & militia kits. They won't be mixed in regiments, so close enough for me!
Still not sure they will fit on 20mm bases. I can trim the integral base down (or completely off) to make individual figures fit, but I'm not certain they'll rank up in a regiment. Especially once their shields are glued on.
Anyone have any basing experience with these guys?
