Darius takes charge of one of the regular squads, designating himself as point.  "Just stay behind me and follow my lead."  He tells them confidently.  "Explorator Thraxis, if you take up the rear-guard position of this squad, we'll do our best to get you through this intact, alright?" He glances at Cortez.  "Captain, if you'd permit me the honor of first blood?  I'll take my squad into the fight just before yours, if that's alright.  I know if things go badly that you'll get us through."<br/><br/>Nodding to the man in the Sentinel walker assigned to his unit, Darius gives him a thumbs up.  "Stay close, but let us engage first.  Once we're engaged with an enemy, then you move into firing position and finish the fight.  OK?"<br/><br/>He activates the advanced optics on his helmet and scans the area for heat signatures.  "And everyone, remember, keep a wary eye on EVERY vent and grate you pass!  Any of them could hide an ambusher trying to flank us!"
