A single man would stand out, clearly in a different uniform and without a firearm raised, instead a laser pistol in it's holster at his side.
"Lady Hanamura you will have to excuse us for the weapons but you do know business with infectees can be nasty, and we can not take chances. Major Smith is disembarking the Sopdu at this moment and will join us in a few minutes. I will ask you to stay calm and as long as you make no sudden movement everything will be done quickly."
With that the man made a small bow and stepped back, taking out a PDA to which he turned his attention as he checked over everything needed for this scan.
To her right Nodoka would notice a airlock has been connected to a vessel outside and from it stepped out the man that took her in for this scan. With a uniform on that had designations of the Overwatch as well as showed his rank was higher than anyone else on this hangar deck currently found, Mark was accompanied with two guards, both heavily protected as well as highly armed.
A minute or so of his walk towards the group she would see the guards make room for him to approach her and her companions.
"Miss Hanamura, pleasure to meet you in person, even though it might not be the best of circumstances. I understand you have other things to attend to, and so do I. We will make our way to the scanning facility and with some luck be done with it quickly."
With that the soldiers would move to the sides of the group, allowing them to follow Mark and his guards which still kept close to him, keeping an eye on the three as well with their guns ready to act. The group would have been escorted with some of the soldiers following behind, their guns now a little lowered but still ready in their hands.
Like that Mark would lead them to the lower section of the station, proceeding to the scanning room which was ready and just waiting for their subjects.
