Should PFCs stand at "Parade Rest" for a SPC?

I was appointed the Barracks Sargent at Fort Been Harrison Indianapolis IN by the Command Sargent Major for 6 Months and regardless of rank (there were E5s and E6s whom upon my inspection of the quarters would address me in parade rest when in the Barracks. However, upon leaving the building the roles reverse. That was 1983. I think it would depend non the Command structure and duties of the Specialist.

Book answer, no s/he is not an NCO it does not apply.

I guess I can see how this might be a little MOS dependent EOD I would never see this being a thing. By the time we get out of AIT we are 6 months from SPC. I could see how this might be more combat arms related as they have different roles they fill that EOD does not have, but still not an NCO not really a thing.

If you are a team leader as a E4 regardless of SPC or CPL you are held responsible for close below you. As a SPC I filled positions of Sgt and SSgt. I tried to keep the atmosphere relaxed but clearly disciplined. I only ever had one issue with a E3 who did not understand how the military works or at least did. As he was disputing my authority to give him direction or 1sgt happened by.
Told PFC X. That anytime he thought I was being out of line or behind my authority in what I told him to do he should come see him. Kid was happy as a pig in mud, until 1Sgt added but you Damn well better have finished the task Specialist Henriksen gave you before you step through my door.

Interesting...Marine Corps Promotion Warrant reads : "I do strictly direct and require all personnel of lesser grade to render obedience to appropriate orders". Good subject to provoke thoughts and comments with regards to discipline expected and demanded at our lower ranks.

Yes, it's simply a show of respect, which is important and part of the developmental process of Soldiering.

My unit has us do it if they are in a team leader position. But not otherwise

Correction required, in the sentence of my post auto correct decided I didn't know what a Pfc was and corrected to Pic instead, dang thing.

I meant to vote pump your breaks high-speed. Last I checked AR 600-8 listed Advancement to Specialist not promotion. As a courtesy to higher rank it's respectful and shows maturity as well as honor for th e uniform, but not required. It's not the Marines. That would be no different than a Pic insisting that a Pv2 stand at parade rest. However, certain duty possisions rate a higher level of respect. Squadleader, section supervisor etc. Situational awareness. Don't be the Pfc that is getting counseled for failure to fallow instructions and a Staff Nco walks by while your arguing with that Spc knowing you are 8up and that Sgt knows you as such. Just stand by, they got something for you to help you figure it out.

It is a unit by unit issue. In some units it is required, but in others it is only required when speaking to PLT SGT or above.

No
