The shoulder insignia patch worn by the South Korean (ROK) soldiers in the film does not correspond to that of any actual unit in the Republic of Korea Army.
If the unit had participated in taking P'yongyang, then the insignia should properly, if worn, that of the ROK 1st Infantry Division, markedly different from the one in the film.
