Congressional inquiries have changed.
During my active duty time (1986-89), congressional inquires were passed down directly to the local battalion/squadron-level commander. There was a 24 hour window to respond, and you better not be late. You also better not BS in your reply.
This response looks like the process has been BS'd to the Nth degree, by someone pay to BS.
The last paragraph looks like higher level cheesedick boilerplate language. Perhaps the USAF does things differently. It could also be that the person submitting the inquiry was in HQ USAF. Given the amount of detail I've seen on the active Army side in discussions on another board, the response looks average. All that information is out there in the commander's hands.
The timeline we had would vary, and typically depend on how long it took to cycle down the chain once it hit post. Usually no more than 72 hours to get the finished response back to brigade for a review and then submission. The bn XO would gather the facts and draft up a response, occasionally asking an interested party to review for accuracy, and then push to the commander for refinement/approval. After the boss got done with it, it would go to the brigade S1 and JA for a quick review before coming back down for signature.
For a vast majority of them, no more than three individuals at the battalion level had any knowledge of the inquiry and the total work load was maybe one/two hour's worth of collective work amongst mainly two people. They just aren't the big stress monster that a lot of junior enlisted folks think they are nowadays. A distraction at worst, but it did occasionally help us find things we were missing or occasionally help us find out the Paratrooper's real issue(other than the fact he didn't actually come to one of us for help first).
The most amusing one we got was a presidential inquiry. We had already answered a congressional inquiry on this individual we were separating and the individual had actually already been separated.
Dear President Obama,
Private X was punished under article 15 UCMJ for X. He was further punished under article 15 UCMJ for Y. He was separated with a General Under Honorable Conditions discharge in accordance with Army Regulation 635-200, Enlisted Administrative Separations, Chapter 14-12B, Patterns of Misconduct on (insert date in the past).
