Army idea I'll probably never use since I can't afford a third army:
>traitor salamanders
>mainly old terran destroyer dudes that got pissy at Vulkan for banning the use of their weapons and demoting them into line soldiers, they think he's a pussy
>they dragged some impatient younger guys into it, with Erebus od Horus promising them their craft will be respected and they'll earn martial glory
Opinions?
