Departing from the experiences of ECOWAS in peace-keeping, this chapter focuses on the creation and development of West Africa’s regional standby force in the context of an African Standby Force (ASF). It discusses ECOWAS’ experience with a view to exploring the extent to which it has informed the role and development of the continental standby force arrangement; indeed whether lessons learned and best practices have influenced the discussion on doctrine and concept of operations of the ASF. The chapter also explores the specific contributions of ECOWAS in this field in order to highlight the region’s very distinct comparative advantage in the process. More specifically, it reflects on issues of coordination, collaboration, and division of labor between the African Union (AU) and the subregions as stipulated in the African peace and security architecture.
