The operators didn't hesitate, even they could recognize that this plan was the only one which offered them any kind of chance at survival.  Even if the excavation site was on the other side of the zerg horde, it was still the only place on this rock which might hold other survivors, not to mention possible escape craft.  Three of the operators immediately began warming up the massive jumpjets which could be used to propel the command center into air.<br/><br/>Meanwhile, the last operator linked Sergeant Ramirez into the security network, and the marine immediately reconfigured some of the turret's targeting data.  Explosions began to rip through the zerg ranks as the turrets shifted more of their fire to the highly explosive rolling zerg.  It came at a cost though, several of the smaller hoppers made it through the holes in the security net, and into the compound.  It took them a while to figure out there were no people about, though, until they finally began to converge at the command center.  The sergeant issued orders over the intercom to her soldiers stationed near the doorway, and the marines began firing through the small shutters near the entrance.  There weren't that many zerg which made it to the command center, and soon the whole building began rumbling and lurching.<br/><br/>"Hold onto something!  As I said, one of the thrusters is damaged!  It won't be a very smooth ride, I'm afraid!"  one of the operators yelled as they could hear hydraulics releasing the locks on the massive landing clamps as the thrusters began gatherings strength underneath the center.
