Which unit ensures the provision of medical services to personnel during an incident?

The medical unit is responsible for ensuring the provision of medical services to personnel during an incident. This includes tasks such as providing first aid, managing emergency medical treatment, and coordinating the medical needs of all responders at the incident site. The medical unit's primary focus is on the health and safety of those involved in the incident and ensuring that appropriate medical care is readily available when needed.

While other units, such as the compensation/claims unit, cost unit, and procurement unit, have important roles in incident management, they do not directly address the medical needs of personnel. The compensation/claims unit deals with financial matters related to injuries or damages, the cost unit focuses on tracking costs related to the incident response, and the procurement unit handles acquiring necessary resources and supplies. None of these units directly provide medical services or care, making the medical unit the correct answer.
