When explaining the course of action of inferior actors in asymmetric conflicts, Guerrilla Warfare is normative. But when illustrated, the examples are only of battles and wars fought on land. Consequently, there seems to be an insufficient amount of studies that show whether Guerrilla Warfare truly is a theory for maritime forces. The purpose of this study is to test if Guerrilla Warfare can explain the procedure of inferior, but successful, maritime forces in asymmetric conflicts. To extract the principles of guerrilla tactics, the controversial thoughts of Tse-tung, Giap and Guevara has been examined. The cases of this study are the Israeli maritime forces in the Yom Kippur war, and the Sea Tigers in the civil war of Sri Lanka. The results show that Guerrilla Warfare, despite similarities, cannot fully explain the tactical procedures of the Israelis. However, Guerrilla Warfare can, despite one difference, explain the tactical procedures of the Sea Tigers. This essay therefore argues that Guerrilla Warfare can be of use for maritime forces in the search of victory despite inferiority.
