Who is responsible for the expansion of the ICS modular organization?

The correct answer is the Logistics Officer because this position plays a critical role within the Incident Command System (ICS) structure, especially when it comes to supporting the operational effectiveness of the entire incident management process. The Logistics Officer is tasked with ensuring that the necessary resources, personnel, and support systems are in place to facilitate the expansion of the ICS organization as needed.

When an incident escalates or additional needs arise, the Logistics Officer helps implement the necessary changes by coordinating the supply and service resources required. This includes the provision of equipment, facilities, and communication systems essential for operational support, thus effectively enabling the expansion of ICS modular organization fluidly.

While other positions such as the Incident Commander and various chief officers may oversee broader operations, it is the Logistics Officer who specifically focuses on the logistical aspects necessary for scaling up the ICS to meet the demands of an evolving incident.
