You always see wildlife firefighters with drip torches. I understand they are used to control/suppress fires, but how does that work? Why does it work as a fire suppressant?

If you burn the grass, it makes a region of “burnt grass” that won’t catch fire. So, you get in front of a fire, using your trucks, and burn up all the grass and easy to burn stuff. When the wildfire gets to that place, it goes out.
Firefighters also use this technique to burn “escape paths” for them to run away through if the fire turns unexpectedly.
