What type of attack involves a quick exterior indirect approach followed by an interior direct fire attack?

The type of attack being described is a transitional attack. In firefighting, a transitional attack typically starts with a brief exterior application of water to cool the fire, reduce heat, and improve conditions inside the structure. This exterior, indirect approach is beneficial in controlling fire spread and protecting firefighters by decreasing the heat load. Once this initial cooling is achieved, firefighters can then make a safe and effective interior direct attack on the main body of the fire.

The transitional attack leverages the advantages of both exterior and interior strategies to maximize effectiveness while ensuring safety. This technique allows firefighters to address the fire immediately without encountering severe conditions inside, making the interior attack more viable.
