How the US Military Might Use Generative AI Chatbots in Targeting Decisions — A Factual Summary

On background, a Defense Department official described to MIT Technology Review a potential workflow in which generative AI chatbots are used to analyze and prioritize lists of candidate targets. According to the official, a list of possible targets could be fed into a generative AI system; operators might then ask the system to evaluate and rank those targets while accounting for operational factors such as aircraft locations. The official said…
