I just re-read the issue again and the two Legionaires JoeZhang are talking about seem to be meant as diversions for the main team which was disguised. In fact the two characters question at the start of the issue what exactly their purpose is which the military captain did not divulge...I think. LOL.
Re-reading it, the idea was that because they had only just become legionnaires, nobody knows their faces and they could pretend to be two kids out on a joyride. At no stage, do any of the bad guys wonder why the male character has a huge legion symbol on his chest or the female is wearing a belt with a large legion belt-buckle.
