Where should the second or third arriving unit typically report to complete a four-sided view?

The second or third arriving unit should typically report to the rear of the structure to complete a four-sided assessment of the situation. This strategy is crucial in firefighting as it ensures that all perspectives of the building are examined, allowing for a comprehensive understanding of the environment, potential hazards, and fire behavior.

By positioning units at the rear, they can gather intelligence about the fire's progress, any potential victims, and the structural integrity of the building from an angle that may not be visible from the front. Furthermore, the rear often provides access points and escape routes that may not be immediately apparent from the sides or front of the building.

Utilizing this approach helps create a well-rounded tactical plan, enhances situational awareness, and supports the safety of personnel engaged in firefighting operations. It is a critical part of effective incident management in suburban settings where homes and buildings can have unique layouts and access challenges.
