Separating Guard & Royal Army

As the ranks of the guard and army are the same, it might be difficult for some to differentiate between the two. To be honest the main differences are who they answer to, and where they're located.
Members of the guard; low-ranking or not, only answer to the commander of the guard and the royal family. Where as soldiers answer to their chain of command.
Members of the guard will always be seen somewhere in the background where any member of the royal family is. (Except in the case of the children; then they are generally seen surrounding the child.)
