Here are some upcoming units from Dreamforge Games called the Eisenkern Heavy Troopers. I really like the look of these. Kind of remind me of GW's Grey Knights, but with more fire power. I could see these guys slowly walking down some city scape blasting away at stuff. These are slated for 32mm scale, but could be used in 28mm/32mm games.
I also like how the uniforms/armor tie in with the Sturmtruppen soldiers. Hopefully Mark will make an even heavier unit that is Terminator size or maybe a little bigger.
