Tau Broadside battlesuit, these mobile artillery units also acts as tank hunters or just anything else that is unfortunate enough to come in range of their twinlinked railguns.
This little fellow is a resin Forgeworld version of the regular Broadsides and thus acts like a commander in his unit. The new Tau are bound to come out within the next two years, and I do hope they are going more for this design that is sleek yet also a bit beefier than what the standard suits look like.
We can only hope :)
