Can a SGT be pinned SSG without ALC if in the IDES process?

(EDIT 2: I've gotten great feedback (mostly) and have addressed the issue with my chain of command and HRC. I knew I would retire/separate at the promotion list grade if my MEB results in discharge, but what I found out is that being in the IDES process "holds my spot." If I am retained, I can then go to ALC and will be promoted upon completion. My main concern was that if I AM retained, I would miss that chance, but HRC has confirmed that I will be given the opportunity to attend the school and pin the rank if I'm not separated/retired. Thanks to most everyone for the great feedback and support. I'm officially un-following this thread, so I'll probably miss any further responses.)

(EDIT: Yes, it's about me. Also, I'm not looking for loopholes, I'm not whining about an unfair system, I'm not griping over what I feel is owed to me, I'm just trying to understand the letter of the law to determine if it's worth further effort or if I should just go to my VA exams, take my rating, and call it a day. Please keep the hooah hooah suck it up rhetoric to a minimum, I'm genuinely just trying to get meaningful advice :) )

Scenario: a solider makes cutoff for promotion to E6, but does not show up on the by-name list and is told it's because they have not been to ALC. Said soldier has been in the IDES/MEB/PEB process pending VA exams and ratings to determine if a medical separation/retirement is to occur and therefore cannot attend ALC. I have scoured the MILPER messages and AR 600-8-19. According to AR 600-8-19, the only requirement for promotion to SSG is completion of WLC/BLC, but the MILPER and the new STEP system says ALC is a requirement. The regulation states that IDES exempts the soldier from requirements such as weapons, APFT, and SRR, but not a word is spoken about ALC.

I do realize that if the soldier is promotable at the time of separation/retirement, they will be compensated and separated/retired at the promotion list grade. That's something, at least, but it's kinda crappy in my opinion that they get denied the promotion otherwise for something that may be no fault of their own.

I feel a combat-related injury that initiates an MEB/PEB shouldn't keep a soldier from getting pinned to a rank they've earned, not because they have chosen not to go to ALC, not because they have failed ALC, but because their injury has prevented it. I understand the reasoning, not filling a slot with a soldier that will otherwise not be able to serve the position or is going to potentially separate shortly afterwards, but if there's no concession or exception it feels like the soldier is being punished for shedding blood for their country.
