Process question -- Stuck in Airborne Holdover

[18XP]

My son and a couple dozen of his buddies are currently cooling their heels in holdover at Sand Hill. Some have been there as long as a month. He called today and said that some 50 guys came in yesterday and most shipped out today while the same 25 or so people are still hanging out, mostly training as "Combat Landscapers." Rumor has it that some have been marked as "No-Show" at 1/507th PIR, but there is no confirming that.

There does seem to be some pattern as most of them are either prior service or former ROTC. The E4 mafia has it that 198th IN is using these guys to revamp the landscaping at a chapel. Again, add salt that to taste.

What I do know is that the stuck guys are not slackers -- they include Infantry OSUT honor graduates and prior service Marines. All are either headed for SFAS or RASP. I'm using this channel in hopes someone here might know someone who knows someone, or in hopes somebody might have a suggestion. They have no listed chain of command, or even a mailing address. The only way to get mail to them is though the local UPS store at $5.00 per item.

Son has re-read Catch-22, which may be a good sign or a bad one. Thoughts?
