I've gone infantry Heavy to get the maximum out of Issodon's Chapter Tactics (Replaces for Stealth). My Idea is that Gurren goes with the Honour Guard in the razorback as a assault or diversion force, Lias goes in the Sternguard Squad. Power armoured Marines and the Contemptor hold my lines/objectives while the scouts move forward or outflank the enemy lines via cover, reliant on their cover saves (5+ in the open) to get them there
