When a leader chooses war to further their goals they sometimes find that the adults choose not to go to war. In some instances the leader is so determined to lead the people or force his / her will upon the people that they will resort to the manipulable children of the society to become his soldiers. Some times through abduction, rape, torture, threats against the child's family or just pure power of will.
A child does not understand the impact of shooting someone the way an adult would and is therefore a better soldier for not questioning if this action is rightly justified. A child is now a soldier with a gun but without formed thought. Guns for brains!
