Does an Air Assault or Airborne badge help Officers get promoted?

Not at all. PME completion, good OERs, and no bad paper (referred OERs, GOMORs) are what matters.

No

My civil Affairs Army Reserve branch offered Airborne and Air Assault depending on which unit you were in.. they also offered language school. But I can tell you that the selection rate back in 2018 was 90% for civil Affairs officers to go from Major to Lieutenant Colonel. Also, with the Army getting rid of so many officers who didn't want to get the vaccine, you have a lot more vacancies than you normally would thanks too bad leadership.
