"Armed conflict" is an umbrella term for a variety of scenarios in which children can be directly or indirectly harmed. Children have played a variety of combat-related roles throughout history. The denial of humanitarian access to children in conflict areas is often a great concern. Children, both girls and boys, even under the age of 15 are cynically included and used as cheap and expendable tools of war, and too many are also exposed to sexual abuse and exploitation in the context of armed groups. This paper briefly introduces the practice of using children as soldiers and the phenomenon of displacement within the context of human security. In then explores some of the links between child soldiering and displacement. International law and standards for protecting children in these situations is described, and hoped to be followed.
