The Ultramarines have been getting a big boost lately as I've managed to finish a nice assortment of models that have been half-done or not done for ages.
The Heavy Bike has been done for a long time, but it was pretty lonely (and vulnerable) so now it's got five pals.
This might be my favorite tank now. I rotated the top-piece (requiring a bit of stressful chopping up of the tank underneath) so the turret sits at the back of the tank rather than the front. While certainly less practical, the look references the original Predator model.
