About "I am a special soldier"?

My understanding ~ purely personal point of view: Miao Lian's greatest wish in this life is to join the special forces brigade, but he failed to pass the medical examination because of an eye injury, and Chen Pai could not continue his special forces career later, but you didn't find that both of them found a feature in Xiaozhuang, that is, they did not play cards according to common sense and met the requirements of special forces.
