History and Practice of Collaboration in Armed Conflict

Chapter 1 describes the historical and contemporary practice of collaboration during times of armed conflict. Key illustrative examples are provided of the principal forms of cooperation with an adversary, namely informing, fighting with enemy forces, and bureaucratic collaboration, as well as other forms of aiding the enemy. With regard to informing, consideration is given to the significance placed on intelligence in warfare and to military doctrine addressing the recruitment and use of informers. The practice of non-state armed groups is also considered in this chapter. The various rationales behind the use of informers collaborators are explored, as are the diverse motivations of those who engage in wartime collaboration. This chapter aims to provide the conceptual and factual foundation for the detailed legal analysis that follows in the subsequent chapters.
