An open lobby posed just as many problems as an open street, perhaps more if you wanted to forebode about the building coming down with them in it rather than in its shadow. She decided to worry instead about the things she could fix. Mule broke the doorway first, shield up and at the front as the group staked its way into the skyscraper's ground floor. Ten meters in and not receiving fire she stepped out to the side, reversing to face the door so that more mobile operators and their wounded could carry the pace into the room. As Chariot looked over the wall outside the promising set of sliding doors Mule crept backward, keeping the rear of the group and turning to look over the elevators herself as they all settled in.

"Might as well kill ourselves as ride separate passenger lifts up without this building cleared." Mule spoke up, looking up at the ceiling and shallowly into experience  Cut cables, no guarantee the line was in service, uncertain resistance further up, there was no other way she thought to put it. "Let's poke deeper in, find the utility section, a freight..."

She cut off as the brutal concussion of jet engines echoed into the room, off streets and windows, shaking the glass fixtures through the lobby as an aircraft held off the ground outside. That was trouble enough. Mule's body spun to follow her head, shield first eclipsing her before her elbow crooked out just past its protective edge as she drew her pistol. Mere seconds for the attackers to dismount, about one for Mule to clock that they weren't already pulped by the gunship's armament. She braced her pistol and opened fire, one pane shattering an instant before the rest disintegrated under the androids' barrage. 

A few impacts whistled and clanged off of the Defender's shield, projectiles glanced wide into the terrain or immediately mangled into a dangerous cloud of spall leaving distinctive black sunbursts across the armor face. She hurried off a set of shots, responding to the contact and staying out to give the rest of the group a chance to cover or retaliate before she joined Chariot in ducking down. Mule drew her arms in, crossing them defensively and angling her shield up over herself as the occasional ricocheting bullet or debris from the mess the androids were making from the lobby clanked off of her. Passing her weapon into her shield hand for a moment, she reached down and patted the scuffed extent of her jacket to make sure her earlier guess was correct. She pushed and prodded the cylinders of a few smoke grenades before putting a finger back up to the radio. No point trying to screech over a fusillade coming from so close.

"Mule here, I have signals. Unknown if enemy is on vis or IR detection, smoke available if we have a way to punch out of this. Over."

With that, she went back to her gun, twisting her wrist and sticking the handgun out over the top of her shield to blindly put a few shots on their new robotic suppressors. The last thing they needed was to go totally cold and let the enemy walk right up to them. This was the fire element, clearly, and already she turned her head to search for some yet unseen avenue that a prospective maneuver element would be using to encircle them. An offshoot hallway undefended, the very elevator shafts they had been about to survey, with their luck an IFV driven through the wall.
