Rotor Cannon Squad Sons of Horus

I think Rotor Cannons might be Tau killers, but even if they are not, they are just too cool not to have a full squad of them. The SoH are really starting to come together. I have a lot of colors I need to work in across three different forces, but you can already see the beginnings of it. I was planning on painting boarding marines, but I might do some work the requisite conversion piece needed for most painting competitions.
