Nowadays, it is becoming more difficult to predict how weapons will be used in battles within the confines of existing laws due to technical advancements. Based on all of these advancements, this paper will analyze two different responsibility regimes and the context of war crimes when discussing the responsibility regime that might result from autonomous weapon activity. Within the scope of this study, it will be discussed who may be responsible for possible violations arising from their activities rather than the responsibility of their fully autonomous vehicles themselves. Under international law, liability may arise in specific ways, regardless of who may be liable under a state's domestic norms. In this context, state responsibility and individual criminal liability are subject to their own unique regimes. The purpose of this study is to discuss the provisions of international law on state responsibility and individual criminal liability in the context of violations committed by autonomous vehicles during armed conflicts.
