Stormtrooper Madness

So there is an apocalypse unit, that Guard can take, GW has it in their archives, where you take three units of stormtroopers, in 3 valkyries. And the big deal here, is when they get out of their transports, they can fire not once, but twice, and I don't mean two shots, I mean, to shooting phases in one turn... thats 4 shots a man. And it can be one at one target and another at another, combine that with pinning first turn from spec ops, and you get, 120 pinning shots, at up to 6 targets... statistically, that's 30 dead marines :D and yeah, it's pricey, but like stormtroopers, it's worth the ridiculous price, for the ridiculous cool
