For as long as the Valkyrie has existed, I've wanted to field an army of Inquisitorial storm troopers mounted in them as my exclusive troop choice. Of course, you'd need a "drop assault" type of rule to make this work at all in 7th, and I'm not to clear on 7th rules yet. That said, when I was thinking about it, I got an idea that came along with one of those grinch-like smiles:
Can I take a bunch of Elysian Valkyries, Vendettas, and Vultures as an unbound detachment, thus gaining the Combat Drop rule, and simply mount a Militarum Tempestus army in those stolen vehicles? Add Inquisitor Lox to the scion command and I'd be in heaven.
