What activates Command and General Staff in a Type 3 incident?

In a Type 3 incident, Command and General Staff are activated when capabilities exceed the initial attack resources. This situation arises when the initial response team recognizes that the situation has escalated beyond what can be effectively managed with the resources at hand. This acknowledgment signifies the need for a more structured command system that can appropriately coordinate additional resources, provide broad situational oversight, and implement comprehensive strategies for managing the incident.

In essence, once the complexity or demands of the incident exceed initial attack size and simplicity, it becomes essential to establish a more formal Command and General Staff structure to manage operations effectively. This also facilitates better communication, resource allocation, and strategic planning, all crucial in complex incidents.

When considering the other options—such as resource availability, the transition to a Type 2 incident, or the discretion of the Incident Commander—these do not directly address the specific triggers that require the activation of the Command and General Staff in a Type 3 incident context. Resource availability may influence decisions, but it is the surpassing of the initial attack's capabilities that distinctly necessitates a structured command response.
