This dream means that you are doing or participating in something important to you recently, but someone doesn't support you, or misunderstood you, and set obstacles for you, which makes you very unhappy. Why are you doing this? Because dreams often express these three situations, one is one's strong desire, the other is heavy psychological pressure, and the third is physical and physiological reaction. Desire will bring dreams, and stress will bring nightmares. If you are in good health recently, this layer can be ignored. This dream of yours has both wishes and pressures. The symbolic meaning of "being a soldier" is "expedition", which means what you want to do. "Demobilization" symbolizes futile efforts and represents your pressure, that is, you are afraid that you can't do it. "Crying" means the reason, that is, someone doesn't support you or misunderstand you, and you release this grievance in your dream.
Saying that you "have never been a soldier" shows that you are very determined about this matter, and you will succeed if you stick to yourself.
