Tired. Picking up cars, testing, collecting oil, adjusting oil and refueling, oil soldiers often have to wear several hats and specialize in many things, so they are very tired in the army. Oil soldiers are on the front line, paying silently. Although they work hard, they never complain. Oil soldiers shoulder the heavy responsibility of providing Hawke with sufficient "oil and grain", and need to overcome various unfavorable factors to ensure the smooth completion of oil support work. Flight support after midnight, especially highlighting the characteristics of oil support, is on standby day and night. Watching the fighters break through the night sky and go straight into the sky, the oil soldiers are always on standby, waiting for the next stage of flight fuel support, ready to cheer for the Eagle.
