Artificial Intelligence (AI) is growing progressively thanks to the evolution of technology. In the military sector, AI has potential applications in every task in which human cognition is needed. As the European Parliament states, “it should only be used as a last resort and be deemed lawful only if subject to human control”. From a legal perspective, the following step is the regulation of a legal framework for AI based on standardisation, governance arrangements, and legislation. However, regulation must be made carefully, as time and calibration are the main factors for a successful change when proceeding with regulations.
