Which of the following punishments can be given under a Summarized Article 15?

Under a Summarized Article 15, the punishment that can be imposed is typically restricted to non-judicial actions that are relatively minor in terms of severity. The correct answer reflects this by indicating a punishment that falls within the limitations set forth for a Summarized Article 15, which tends to include short periods of confinement or the imposition of restrictions on movement.

The option of 14 days restriction is a permissible punishment as it aligns with the guidelines that govern non-judicial punishments, allowing commanders to place limitations on an individual's activities for a fixed period. This type of punishment is used as a corrective measure that allows for discipline without resorting to more severe judicial action.

Other options like 7 days confinement and 30 days of hard labor exceed the bounds of punishment typically available under a Summarized Article 15 due to their increasing severity. Dismissal from service is also not an option under a Summarized Article 15, as that denotes a more serious level of disciplinary action typically addressed in court-martial proceedings, not through non-judicial punishment. Thus, the correct choice reflects an appropriate and permissible disciplinary action within the framework of a Summarized Article 15.
