Which of the following are effective methods to support mobile attack?

The selection of backpack pumps and hand tools as effective methods to support mobile attack is grounded in their practicality and effectiveness in wildland firefighting scenarios. Backpack pumps allow firefighters to carry a manageable amount of water directly to the area in need, providing targeted suppression efforts in situations where larger apparatus may not be able to access. This mobility is crucial for rapidly shifting fire behavior and helps in directly combating flames in various terrains.

Hand tools, such as shovels and McLeod tools, play an essential role in creating fire lines, removing vegetation, and controlling spot fires. These tools enable firefighters to actively engage with the fire at close range and to adjust their tactics quickly based on the fire's movement.

The combination of these tools supports a proactive approach in mobile attack strategies, facilitating a quick and efficient response to fire spread. This approach is especially important in managing wildfires, where conditions can change rapidly, requiring flexible and immediate action.
