Observer.
This is a rather important position in a forest fire.
Just like in a war, you need to know the number of enemies, their formation, and whether they have changed their direction of attack.
Observers usually stand in the place with the most open view, testing wind speed and direction while observing the fire situation, so they can notify the relevant personnel to respond in a timely manner.
For example, 10:55 a.m. was the last evacuation time.
This meant that if one hadn't left the danger zone by 10:55 a.m., their life was basically in jeopardy. This was a timely judgment made by the observer, requiring rescue personnel with considerable experience.
Yunmiao Mountain was not the main battleground of the disaster, so in order to evacuate Yunmiao Mountain orderly and safely, while also controlling the fire, it required a professional to command and coordinate.
