MTOE to MTOE unit move; how will this impact my career?
Have you considered applying for Instructor Duty?
Have you read through the CMF's NCOPD Guide?

SGT Tiner,
Having two TOE unit will not hurt you now but, you'll want diversity in the future; you can get some diversity by going from light to armored and changing positions, etc. Do you know which unit at Hood you're going to? you could be going from Infantry to a CSH or sustainment BDE which, even though another TOE unit, provides diversity on your ERB also. I see you are promotable so as you time gets closer to your next PCS assignment you should try to go into a special duty such as Drill, recruiter, or Instructor. There are other special duties out there but those are the most common. This will be important as you look towards SFC. Make sure you are studying the career map. I know plenty of SFC's who have not been in a hospital but few had not special duty. I like to tell my Soldiers to always work like your one pay grade higher than you are and focus on promotion two pay grades up, that way the next one should take care of itself and it always fills that "5 year plan" people talk about. Another thing you should do is try and get into a school that reflects on your ERB at least once a year. It can be an NCOES, FBCB2, EO, SHARP, etc. Degree's are big for SFC and MSG so you should be on that stuff now. It also doesn't hurt to have some community volunteer time under your belt, this can reflect in your NCOER's or as the MOVSM in your awards section of your ERB. As deployments wind down, EFMB is going to become a discriminator again like it was before OEF/OIF so that's something you should do if you haven't already. Look at the SFC and MSG selection board AAR's and follow along, that's not to say if you do exactly that, you'll get promoted ahead of anyone else but, those things won't hold you back either. Lastly, always keep your ERB up to date, don't wait on the boards.
Hope this all helps, and good luck.
I would suggest scanning the MOS search within RP and finding some senior 68Ws and asking them directly, we also many CSMs on the site that could give some valuable input as well, maybe even some in the field for direct support, give it a try and see what you can find.
Good luck in your search, take care and have a safe and happy holidays.
