Flank = Sides, always.

You have to put yourself at the 10 or 4 of your enemy if the pointing of him is 12. That way you have to move a little to get HT up, then go for ID-Dis-CT and then for the TTT.

Impulse Drive is good, Disembowel and Chaos Trust are musts. (Besides Chaos Trust is the best looking skill of our arsenal and is how most of our skills should look, Burmecian Dragoon Freya would be proud of it)
