On the show itself, we encounter a variety of low-to-medium rank enlisted/NCOs in both the Starfleet and the MACOs but no senior NCOs (or even the names of such). However, the Enterprise Relaunch books identify the rank of Master Sergeant in the MACOs (borne by some Detachment/Platoon Sergeants) and Section 31: Control mentions the rank of Warrant Officer in the (R & D department) of Starfleet.
Master Sergeant may be roughly equivalent to one or both of the Chief and Senior Chief ranks held by Miles O'Brien (USAF MSgt ranks with naval CPO, USA MSG & USMC MSgt ranks with SCPO), however Warrant Officers can be either intermediate specialist officers (US Armed Forces only) or equivalent to US NCO ranks of E8 & E9.
So, my question is, which - if either - of the above is it credible that a non-prior service individual with academic credentials as a "graduate research assistant" (at least BSc, likely MSc?) could have been appointed to? Assuming that said post broadly aligned with her academics?
