The Military Impact of Foreign Fighters on the Battlefield: The Case of the ISIL

  • Chapter
  • First Online:
Foreign Fighters under International Law and Beyond

Abstract

The so-called ‘foreign fighters’ are the most controversial example of the increasing relevance of transnational actors in global politics and contemporary warfare. The border between domestic and international security is becoming blurred due to the potential adverse impacts of these fighters, mainly in terms of consequences related to their experience on the ground (blowback effects, terrorist attacks, radical propaganda, etc.). Despite a mounting interest in this issue, scarce attention has been devoted to the mechanisms through which these foreign fighters are trained and, above all, the ways in which they spread military innovation and adapt across conflicts and crises. Looking at the case study of ISIL (Islamic State of Iraq and the Levant), this chapter will investigate the patterns of the military involvement on the battlefield of foreign fighters as well as their role in the process of elaboration and diffusion of approaches, tactics and lessons learnt.

The author is Assistant Professor at the University of Genoa.

    Another useful definition is provided by Hegghammer, who considers a ‘foreign fighter’ to be an agent who: ‘Has joined, and operates within the confines of, an insurgency; Lacks citizenship of the conflict State or kinship links to its warring factions; Lacks affiliation to an official military organization; Is unpaid’. Hegghammer 2011, p. 53.

    After the conflict in Afghanistan in the 1980s, the concept of foreign fighters became synonymous with ‘jihadists’. Despite the limited fighting role of the Arab Afghans on the battlefield, the importance of that period lies in the training, socialization, and networking conducted by those fighters. Unlike in the past, they did not come home after the war, but started a new ‘transnational war’.

    According to the ICSR, the countries that provided the highest numbers of foreign fighters are Tunisia, Morocco, Jordan, Turkey, and Saudi Arabia.

ISIL has no formal affiliation with Al Qaeda. The Al-Nusra Front, Al-Qaeda’s branch in Syria, developed a strong rivalry against ISIL.

    Foreign fighters played a relevant role in such activities, also thanks to their previous knowledge and expertise in ‘cyber battles’. Ibid.
