Can a Specialist make a Private stand at Parade Rest for him?

IMHO - no - not for a SPC, unless that SPC was holding and appointed to a NCO position - then it is the position that you are respecting. For me, just give me the curtesy of going to parade rest when you approach me, unless it is for corrective purposes, I always said "relax" - no reason to keep someone at that position for longer then curtesy demands.

When I was a spec 4 profitable, i had my own squad of 13 people. There were times when I had to put privates and even non-promotable spec 4s at parade rest. It was rare but sometimes had to be done. At that time in our unit, a spec 4 promotable was considered an NCO by the rest of the chain of command

if he is a Spc 4 tell him to get a job. If he is a Spc 6 and above better listen

What we have here is a lack of clarity in the question. If we read it as any Specialist and any Private, then the answer is no. If we consider the specific circumstance where the Specialist is (either temporarily or permanently) in a chain of command position re the Private, then the parade rest position might be appropriate.

It depends on a couple of things. Yes, that’s what the regulation says but if the SPC is holding a position of command (say the PSGT designated them in command of the platoon, or 1SG, etc) then they are afforded the same respect as if the PSG was standing there. Or if they are assigned to a position that is normally held by a higher ranking enlisted. It also depends on what the command staff of the unit designated. In my last unit, if a SPC told a PV1 to do something, they were to do it and show proper respect; this was 15 years ago though.

Might depend on the size of the SPC

Depends on your unit. If you are a SPC and a team leader or section leader. You can not require it unless you are a CPL. in my unit, when I was promotable the NCOs in my unit required those of lower rank to stand at paraide rest.

Yes but only in certain situations. General military Authority dictates that if the specialist is the ranking individual and is in charge of that area or facility yes they can as they are in a leadership position. When a non-commissioned officer delegates the authority to a specialist even for a detail as long as they're in charge of that detail yes they then have the authority of the noncommissioned officer. The Specialist can bring a hundred privates to the position of attention if they are the ranking individual in that area at that time, provided they are tasked by an NCO to take command of that area. It can happen and it will happen there will be a time when a specialist will be the highest ranking person in the area there will be no ncos around and you will have to take command do what you have to do but I understand when the ncos do eventually show up maybe a day later every command you gave will fall squarely on your shoulders they say that an NCO should be one who seeks responsibility and takes responsibility for their own actions so be prepared for that

Glad to re up with you man
