[X][MRR] Leave as Captain and appoint to shore billet
As others have said, she helped save the Federation, and as a protege of Nash, Samhara may want to follow Nash's footsteps for a second FYM.
[X][NASH] Assign to Sector Task Force <Gabriel Border Zone>
I agree with what others have said about Nash's preferences, along with her 4.5 years of TIR.
In addition, we're sending so many ships over to the GBZ, that we're at the point that we need a third task force.
Consider: The GBZ currently (Q3) has 17 ships: 2 Excelsiors, 5 Connie-Bs, 1 blooded Constie, and 9 Miranda-As. Next year, this is scheduled (albeit subject to change) to grow to 23 ships: 1 Excelsior-A, 1 Excelsior, 5 Connie-Bs, 4 Rennies, 1 Centaur-A, 11 Miranda-As. That's a shitload of ships.
The largest task force ever commanded by a Commodore has been 10 ships: TF6 in the Arcadian crisis, commanded by Iorinn Grann. But this was a defensive fleet, made for catching any mentat/Licori intrusions.
The largest non-defense task force ever commanded by a Commodore has been 9 ships: TF2 in the Syndicate campaign (the Amarki fleet) and TF2 in the Arcadian crisis, both commanded by Nash ka'Sharren. The other Arcadian crisis task forces were either 7 or 8 ships. The GBZ task forces maxed out at 6 ships IIRC.
So the GBZ will need three task forces by next year, and that's an opening for Nash.
[ ][THUIR] No preference
I don't know whether Thuir prefers promotion or other Commodore-level positions for experience, or what's best for him and Starfleet here, so I'll abstain on this vote.
Regardless of his position, no doubt he'll still be continuing presentations of "
Not Touching Things 101"
[X][ROCK] Transfer to Ship Design Bureau
Theoretically, Starfleet Engineering Command offers the most hands-on approach to space rocks™.
Problem: We're sorely lacking in engineering ships. We only have 6 right now, and I don't recall any more being built at the moment. (I think we've been concentrating on prospectors, freighters, cargo ships, and the hospital ship prototype instead.)
So for now, let's let Straak work his magic in the SDB in the mineralogy research group.
[X][SAAVIK] Assign to Task Force - Ferasa Sector
Don't have a strong opinion here, but if she's proved to be as much as a trouble magnet as she has, here is as a good place as any.
Bonus: this is N'Gir's heartland
