Personally in IMTU the TC Scouts ditch the NCO ranks entirely, but the  ranked exec/admin stuff is great fun.  Why eliminate the hilarity of  Scouts outsmarting their own bureaucracy?
Be practically a rite of passage or even a form of training in the individualistic 'get er done' ethos of the service.
Hmmm, though, now that I think of it, how would Scouts show accomplishment and count coup without the rank and medals?
Ahh, I got it.  Mission patches.
For  difficult, strenuous, dangerous, important and/or endurance missions,  the Scouts would make a mission patch.  This would be a combination of  the NASA mission patch, unofficial military/intel unit patches, and  plane nose art.
Unofficially recognized or awarded, the mission  patches would tell the story of the mission, sometimes having the  mission member names around it like an Apollo patch, sometimes profane  or lewd, sometimes heartbreaking as it records fellow member losses.
The Scouts would put these all on their mission jacket, typically a standard issue survival jacket.
They  still have their official dress uniform for ceremonies and impressing  the inspectors or nobles that need to be assured the Scout Service can  clean up well, but the mission jacket is the internally recognized  'dress jacket', often lovingly protected or left at base for  safekeeping.
When scouts gather, or perhaps at the start of a  mission during intros to the team, they wear the mission jacket.   Provides a fast assessment of what the other scouts have done, a natural  talking point, and is often a more effective resume then the official  record.
Surviving mission leaders typically 'approve' the mission  patch, but any of the members can design it.  Usually done after the  mission, as most missions are 'routine' and not considered worthy of  patches.
Most scouts will have only one X-boat patch with a  number indicating years and typically an image playing up either the  relaxation of the x-boat posting, or going stir crazy.
Assuming  the mission jacket survives the wearer's demise, they are often  treasured heirlooms and represent the sum total of the scout's career,  official and detached duty.
