Fun fact #1

Interestingly enough, the Chaos marine Rhino comes with a combi-bolter as is, and in the vehicle options it states that it can take not only a combi-weapon for 10 pts, but also can take a second combi-bolter for 5, like the rest of the vehicles can... Fo for 15 points you have a Rhino with 3 bolters, two of which are twin-linked.
Not that it's going to do too much, lol. But fun to think of a rhino with 3 bolters (and 5 gin barrels), a single shot melta AND a havoc laincher with dude blasting out the top hatch with their own guns.
Its almost like the Warpsmiths are taking a page out of the Ork codex astartes equivalent: MOAR DAKKA!
