After they finished their training, soldiers enter the base as a private, and gradually move up the rank up to sergeant over time (Kim Jaejoong currently is PFC: Private First Class). Their specialties are already assigned according to their abilities. The life at the bases can differ vastly depending on where the base is, and what your specialty is.
Kim Jaejoong belongs to 55th Infantry Division Military Band.
We already informed that being part of Military Band means he will have to do his military service like any other active duty service soldier (Active duty in the Army refers to working full-time as a soldier), but also to ADD his activities as a member of Military Band, this is the specialty Kim Jaejoong is part of, and it was understandable because where else he could display his singing abilities without losing his touch by being on hiatus as singer for almost 2 years?.
Here we have a more detailed explanation of the meaning of being part of Military Band from the army medic’s point of view:
