The system designed to resolve problems at the lowest level is known as the chain of command. This framework is essential in military operations, as it promotes the efficient resolution of issues by empowering non-commissioned officers (NCOs) and junior personnel to address challenges immediately within their scope of authority.

The chain of command emphasizes the importance of ensuring that problems are articulated and handled closest to the point of occurrence. This principle not only fosters initiative among lower-ranking personnel but also streamlines communication and decision-making processes. By effectively addressing issues at their source, the overall effectiveness and morale of the unit can be significantly enhanced.

Other options do not specifically focus on the lowest level resolution of problems. A support system typically refers to the resources and assistance provided to personnel, often at higher levels of the organization. Crisis management involves handling large-scale emergencies and is not limited to resolving day-to-day operational issues. Decision hierarchy speaks to the layers of authority within an organization but does not emphasize the importance of lower-level problem resolution.
