Sure if you want a brainwashed idiot whose certain to die first to prove how super serial things are (or to be used as spiffy paint, as the case may be).
at least you get a cool organ-pipe that shoots missles
yeah...being badass massacring thousands of heretics .... also (i am shure i already mentioned) melta guns and flamethrowers...
Dude have you read the fluff? SoB exist to all die horribly in massacres so the true heroes (inquisitor, Space marine,etc) can have a sufficient fount of righteous indignation when he arrives to save the day.
I'm also against SoB in this case, simply because the melta would cook the admiral when he's that close. Plus, given the, uh, "zeal" that Kaga does her job with, SHE would be the melta queen. The Echlissarchy does condone hatred as a virtue.
