I like the apc in the 2nd pic and the armoured car in the 3rd. I think they would look greatin an IG or PDF army.
Yeah, we flew our space church across 500 light years to get to this planet taken over by the space orks. Now we're going to drop from orbit in buckets and run out and shoot pistols and hit people in the head with chainsaws. Yeaaaah Ultramarines!
