Can a Sergeant be reduced one (1) grade in a Company Grade Article 15?

In the context of a Company Grade Article 15, a Sergeant cannot be reduced one grade due to the provisions outlined in the Uniform Code of Military Justice (UCMJ) and related military regulations. Specifically, Article 15 deals with non-judicial punishment, which allows for disciplinary actions without a court-martial.

For Company Grade Article 15s, the maximum punishment that can be imposed includes a reduction in rank or grade, but for a Sergeant (E-5), the only applicable reduction would be to Corporal (E-4). In this case, a mid-grade enlisted service member such as a Sergeant is not eligible for a reduction to E-4 through a Company Grade Article 15.

This means that the correct response reflects the limitations set by military regulations regarding reductions initiated through this form of non-judicial punishment, emphasizing that a Sergeant cannot be reduced to a lower rank solely under the decision of a Company Grade Article 15, thus making the answer "B" accurate.
