Are you sure that with Raing nearby and Tessar on the tower, a defensive tactic wouldn't be more useful?
Although, we could make an offensive move on the first turn, and then defend (just so that Eldar and Libar don't receive a speed penalty).
Or we could defend the whole time, but that might hinder us from quickly eliminating Daran. And we need to make sure that the infiltrators don't receive a speed penalty either.
