Hmmm, ya, I am leaning to Book 6 done by LBB1/COTI, Scouts are the line guys, Bureaucrats are the senior officers, the officers insist on wearing their dress duds while the line scouts wear their mission jackets or working suits/exploration dress on all but formal occasions.
Any bureaucrat that has not been promoted might be sent out on 'field surveys', on missions where they are to observe, probably due to a rule that Scout Officers cannot be in the field and also to season/prepare the new bureaucrat with a sense of what goes on 'out there' and why the counter-intuitive organization mix.
More fish out of water fun, cause what's more useless on a Scout mission then a bureaucrat? A junior bureaucrat with absolutely no useful skills.
Eh, got to looking at the COTI pregen character list for non-ranked bureaucrats, and found most didn't have Admin. Some are useless, others useful.
Struck me that a scout crew would like having a bureaucrat guy along in a yard goat capacity to requisition all the good stuff, get good coffeemakers and grub on board using their admin skills, etc.
Also, noted a lot of examples of unranked specialist types on that list, including a Recruiting-3 guy (HR in spaaaaaaaaace) and a Computer-6.
Could be the unranked serve as sort of Scout Warrant Officers, technically outranking the line scouts but not being a Scout Officer?
Still fish out of water, remember bureaucrats specifically get the no-gun skill negative, and pretty much no space skills at all.
sigh... time to flog the dead putrefying horse .... whap whap whap....
