"These Guiding Principles are intended to serve the purpose of promoting and spreading knowledge of international humanitarian law and, in particular, of implementing the provisions protecting children affected by armed conflicts, especially children associated or previously associated with armed forces or armed groups. The Guiding Principles suggest a number of practical, regulatory and legal measures as means to encourage States to improve such protection. They are based mainly on binding international rules (taking into account the specific obligations of all relevant treaties and of customary law). They also refer to widely accepted instruments of a non-binding character ("soft law"). A checklist of the main obligations regarding children associated with armed forces and armed groups is provided in Annex IV"
