They don't necessarily offer Airborne school, add-on schools are hard to get as we currently have kind of a mean branch manager. If you get it in your contract then that's a different story. Additionally, if your follow-on assignment happens to be an airborne assignment, then you will most likely go to airborne school. There can be a lot of school options for us but it usually depends upon the need. For example, you can go to a strategic debriefing course if there is a need for a strategic debriefing ASI 35L in your unit.
I suppose the short answer is, its the same as the rest of the Army.
