How much does the SFC board favor Air Assault and Airborne completion?

Dude, you got some serious time ahead of you before you're eligible for SFC look. I certainly applaud your enthusiasm and drive. If you can get both, then get both. If not, I'd recommend Recruiter and Drill Sergeant. Look at additional duties as well. Follow the Army Career Path for 12B. Have your degree.

this is a confusing question. Your current rank is listed as SGT so you have a while to worry about SFC. ....if you can go to these schools then gom

I certainly commend your forward-thinking mindset. It's good to plan ahead and be proactive instead of reactive.

First, your unit can't send you to Airborne school. In order for you to go to Airborne school you have to go TDY enroute to an Airborne assignment. As far as the board is concerned, being in an Airborne assignment is usually rated higher than a non airborne one, and airborne Soldiers serving in Airborne assignments do have a higher selection rate for most MOS's.

The single most influential thing to the board is your position and your NCOERs from that position. A SSG serving in a SFC position like PSG, successfully, will rate higher than a high speed SSG serving in a SSG position with all the badges. So perform well, take the hard jobs, and get selected to take the senior positions in your organization that lead to promotion.

Everyone will tell you what you need to do well in the boards eyes, but that is all speculation. You can go right to the AAR notes where the board members tell you what criteria they used to grade you, what was considered competitive, what was not considered competitive, and what the top rated NCOs possessed.

Next go to the HRC Enlisted Promotion Page and watch the class about how the board scores each person. That way you'll understand about half of what the AAR is talking ABOUT. More importantly you'll see where schools like schools like AAS sit on value to the board. FYI, it's an Additional Skill Identifier not a Special Qualification Identifier, so unless you're actively using the skill it doesn't mean much to the board. Basically, if two Soldiers are exactly the same and one has AAS and the other doesn't, the first one will break the tie.

Finally, if you have the time, spend it on your education. At some point education becomes a deciding factor for every MOS on the boards. In my MOS it's almost impossible to make SFC without at least an associate and MSG without a Bachelors. For others it might be you can't make MSG without an associate. Point is you don't want to be staring down the board trying to get promoted but you still have another year or more of school before you're competitive. Start now, take one class at a time, and in a few years you'll have an associate with an almost perfect GPA.
