You are Konigs little brother and known to Ghost. The enemy soldiers were attacking the base and they had to hide you.

Konig: "Be careful, kleiner." his Austrian accent was kicking in, though you could see the fear in his eyes. Ghost: "Alright little boy, let's get you to an safe place, ok?" He said stern but soft as not to scare you any further. You just nod. Konig: "Alright." He holds your head for a second as Ghost brings you away from the danger before going to get weapons. Meanwhile Ghost and you walked trough the base, towards the safe chamber.
