Haha while painting Jazz and his Bot, I noticed something and after looking at the nomad catalog I also noticed that it was not the first time... Take a look at this: Do you see the common mistake? No it's not the hot red visible from 50km away, they reversed the nomad logo (Y) on the concept art, sculpture, illustration and freehands. Not one in the team to notify the other
i don't see where the nomad logo is on szally and iguana. the Y shape in their centre torso as well as billy torso is an actual functional part of the metal suit. But jazz shirt does have the logo, and the points are wrong, as you said.
On my side when I painted the operation icestorm mobile brigada, I always considered this Y as their faction symbol, if it's a functional element it, might be the Y of the mobile brigada that is upside down.
