Which aerial firefighting tactic involves dropping water or fire retardant directly in the path of an advancing fire?

The tactic of dropping water or fire retardant directly in the path of an advancing fire is known as a direct attack. This approach aims to suppress the fire as it actively spreads by targeting it directly. By applying the suppressive agent where the fire is burning, firefighters can more effectively reduce its intensity and slow its advancement.

This method is particularly useful when the fire is manageable and the safety of the personnel and equipment allows for a direct engagement with the flames. It contrasts with other tactics such as indirect attack, which involves establishing a barrier by creating firebreaks or using other means to control the fire's spread from a distance, often requiring the fire itself to burn out before it reaches these barriers. Overall, the direct attack is a proactive maneuver that can help stabilize the situation if conditions permit.
