Is taking apart a soldier's ACH when it has been left unattended hazing or corrective action?

Disassembling a Soldiers ACH because they left it unattended, IMHO, does not constitute Corrective Action. Now, assigning that Soldier to PCC/PCI (say, for a week or every time y'all go to the field or to the range) other Soldiers in the section/squad to ensure everyone has their ACH, that would be a good Corrective Action.

I agree with the anonymous 1SG. Nothing scares a Soldier more than standing on the 1SG's carpet knowing they messed up. Really, it's as simple as this: Grab your ACH and go see the 1SG at 0900. Be prepared for sweating bullets.

Yeah, you could disassemble it. Some pieces will probably get lost that will take you days to replace and be more of a pain to you than them. Nothing wrong with it, just as a future SSG you need to expand your toolbox past that of a Buck SGT.

SGT(P) (Join to see), Lots of great replies that say the same thing.

If this is your idea, don't do it. Take the advice in regulatory guidance and train your soldiers the importance of accountability by explaining the "why" and base your corrective training around that. Disassembling an ACH that was left unattended only serves to reinforce the ability to assemble the thing back together. The "why" in that case is if you leave your ACH unattended someone is going to mess with it, which doesn't enforce the importance of having it and wearing it. The Soldier will just get good at putting it back together. Personally, I like MSG (Join to see)'s idea of "assigning that Soldier to PCC/PCI (say, for a week or every time y'all go to the field or to the range) other Soldiers in the section/squad to ensure everyone has their ACH". It also has the side benefit of preparing the Soldier for leadership responsibility.

If it happened to one of your Soldiers, make a big deal about it; professionally. Too often I see stuff like this happen and junior NCOs "let it go" because a peer did it. Don't let other people train your Soldiers.
