I've been popping back and forth between the deathwatch marines, and the tanks in my IG force, to keep things interesting.
I recently finished... (looking up names online) Ennon Sorrick (yeesh). Not the most interesting pose in the set, to be sure, but the mechanical details are neat.
Not that I need more marines. I dunno, might just sell off the models in a batch before I finish them. Painting marines just doesn't do it for me anymore.
