Kingmaker looked out the window, as the helicopter came in to land, watching Cassie's feed, watching her single-handedly land like a fucking boss, kicking over a guard on the roof, before then moving in. She was good at this, Martin reminded himself. Liberty could do one hell of a lot of damage, but he knew she had to be controlled, and not completely let off like a loose cannon, killing everything in sight.  She was moving in, and from what he could see, she was moving tactically and precisely, like a black cat.
"Understood, Liberty. Bugcatcher, keep things on the straight and narrow, keep watching."

Thom watched on, getting ready to fire on anything that moved, covering Lancaster inside. He knew that the other agent would have this under control, and would be able to take these motherfuckers apart one by one, he was skilled at it, and would not stop at anything, no doubt.
"Shit, I see a runner!" Thom said, as he sent a burst down range from the PDW, clipping the terrorist in his sights, as he moved around, heading through the gates with his usual low profile, taking the man down with a simple burst, as he moved around, the suited individual adjusting his position to behind a pile of rubble, continuing to observe as the noise of gunfire could be heard inside, as well as several very dead terrorists.
"Okay, keep going, we have nothing out here, do what you do best!"

Kingmaker looked over at Cassie's feed once more, looking over, as he saw her take down the guard, then add a panicked response.
"Shit, I see it. Okay, move fast. Get the back door installed, and get out. Bugcatcher, talk her through this one. I want eyes, if a single detail moves up the stairs, you bail from that building and don't make a sound. Remember your plan, and go to Plan B if you only have to. Let's not make this a big deal." Martin simply said, 
"If you have to, Bugcatcher, use non-lethal means to confuse them. Sprinklers, " Martin finished that transmission, but it was not before his  his headset buzzed. It was a different frequency picking in, and it would only ever happen if it were urgent. Martin could tell it wasn't a good thing at all, this was a spanner in the works waiting to be heard..

"This is Post Zulu, we've got radio traffic from the City Airport intercepted, we've got an unidentified quadrotor UAV in the air, closing in on your target building! We're working on it's identity, stand by!" The man on the other end was panicky, as he heard the individual go over it, Post Zulu being a listening station run by GCHQ in London, to intercept radio transmissions. It was a support asset, and not expected to be involved...but Martin could have guessed that it was of a priority to a listening station such as theirs to be on a need to know basis, and let them know when they saw something out of the ordinary.
"They're not ours....fuck, Bugcatcher, get onto it, we've got a separate intrusion...those drones aren't on their network!" Martin simply said on his own channel for the second part of his sentence, as he looked across at the MI6 building, as the helicopter came into land, Martin aleady opening the door.
"If you tell me they're armed, then someone is looking to do damage recovery work...Liberty, get whatever the hell you are doing and get out of there, double time!" He added, looking out as he stepped out of the helicopter, quickly. He had to make his way to Bugcatcher's office, and he knew full well that what was happening now could be anything. This wasn't the building security, this was someone looking to knock out something in the building.

The drone operator sat in a park, looking down at the tablet he had in his hands. The man was of a Central Asian decent, and he had simply been paid to run the drone, from this position, into restricted airspace. He was simply told to fly it to the target building, and using it's armament, disable the network that his employers wanted gone. No back doors, merely to send a message to them, that their branch was marked for execution. He was a former inteligence operative, his dark tanned skin of an Iranian origin, and service in the country something he remembered. But this was not for them, it was far deeper than that. It was a chance. Manoeuvring the drone, he engaged the FLIR cameras and saw in on the guards, knowing it's payload was far more than just observation cameras. Once this was done, he would leave, and the people that had the server would realize that they were being punished for their failings to protect a man that ought to have never been taken. And now, he was close, closer than ever to getting his job done, as he put his hood up.
