TC, I may be a little out of date, to get a commission as a CS you will still need to pass OASC and attend IOT. With an RAFR commission you will have. Seniority commensurate with your rank, but junior to all regular officers of the same rank. Your responsibilities remain identical to all the officers you already know.
Writing assessments for a CS is no different from any other assessments except that unlike a military assessment which affects promotion and ultimately pay, for a CS your appraisal will affect whether they get an annual bonus.
You will also be irked receiving the pay of a cpl if you have to report on a sgt .
