Foreign fighter experience and impact

Abstract

ABSTRACT This paper examines the relationship between prior conflict experience and the impact of foreign fighters on armed groups. This paper addresses the findings in existing research that describes foreign fighters as both assets and liabilities by disaggregating foreign fighters into first-conflict foreign fighters and veteran foreign fighters. While prior experience determines the potential impact of foreign fighters, I introduce the concept of foreign fighter integration to understand how this experience is utilized or leveraged by armed groups. The theory-building framework helps explain why we see certain groups leverage foreign fighters in ways that shape their repertoires of violence, tactics, or even ideology, while, in other instances, the influence of foreign fighters appears to be limited – with any consequent effects restricted to the small factions into which foreign fighters have been assigned. Using this theoretical framework of experience and integration, I re-examine in the cases Somalia and Bosnia and Herzegovina to demonstrate how and where foreign fighters impact armed groups.
