Study to analyze vulnerability for artificial intelligence-enabled military applications (a) Study Not later than one year after the date of the enactment of this Act, the Secretary of Defense shall complete a study to assess the functionality of artificial intelligence-enabled military applications, research and development needs related to such applications, and vulnerabilities to the privacy, security, and accuracy of such applications. (b) Elements The study under subsection (a) shall include the following: (1) An assessment of research and development efforts, including transition pathways, needed to advance explainable and interpretable artificial intelligence-enabled military applications, including the capability to assess the architectures, data models, and algorithms underlying such applications. (2) An assessment of any potential risks to the privacy, security, or accuracy of the architectures, data models, or algorithms underlying artificial intelligence-enabled military applications, including the following: (A) Individual foundational artificial intelligence models, including the adequacy of existing testing, training, and auditing for such models to ensure such models may be properly assessed over time. (B) The interactions of multiple artificial intelligence-enabled military applications and how such interactions may affect the ability to detect and assess new, complex, and emergent behavior among individual agents, as well as the collective effect of such interactions on risks to the privacy, security, and accuracy of such applications over time. (C) The effect of increased agency in artificial intelligence-enabled military applications and
