During the mission, I had to follow the

instructions of my superiors
In the mission, I had to follow the instructions of my superiors to run around between the dorsal turret and the tail gun to hit the German fighters, and my superiors also told me the direction the German planes were coming from, using the clockwise direction, such as 12 o'clock, 6 o'clock, etc.. If the wing of my own plane was shot, my superiors would tell me to cut the fuel line of that wing (the fuel line switch to be closed was flashing gold).
