A straight stream is briefly discharged through a window from the building exterior. This is typical of which type of attack?

The discharge of a straight stream through a window from the outside of a building is characteristic of a transitional attack. This attack strategy is typically utilized when firefighters aim to cool the fire conditions before entry. By applying water from outside the structure, they can reduce the heat and smoke inside the building, making it safer for crews to enter subsequently for interior fire suppression and search and rescue operations.

The transitional approach helps to control the fire's development and can halt the spread of flames while preparing for a more effective and direct method of extinguishing the fire once conditions are improved. Understanding this tactic is crucial for firefighters to maximize safety and effectiveness during operations.
