What is one non-punitive measure available to commanders for enforcing discipline?

The non-punitive measure available to commanders for enforcing discipline is extra military instruction. This approach allows commanders to address performance issues by providing additional training or mentorship to service members, rather than resorting to punitive actions that could negatively affect a soldier’s record and future opportunities. Extra military instruction focuses on correcting behavior through constructive guidance and reinforcing skills, thereby promoting personal and professional growth.

In contrast, options like reduction in rank, separation from service, and confinement represent punitive measures that can have lasting impacts on a service member's career and morale. These actions are more severe and are typically used only when less invasive options have failed or when a situation warrants immediate disciplinary action. Thus, extra military instruction serves as a proactive and positive means of maintaining discipline, emphasizing improvement rather than punishment.
