A child soldier is a person under the age of 18 who is recruited or used by armed forces or groups in conflict. These children may be forced to fight, serve as messengers, or perform other roles in warfare. The use of child soldiers is a violation of international law and is condemned by organizations such as the United Nations. Child soldiers often face severe physical and psychological consequences due to their experiences. They may be subjected to violence, exploitation, and trauma, which can affect their development and future. Efforts to rehabilitate and reintegrate former child soldiers into society are ongoing in many regions affected by conflict.
