National Security Law (Code 10)


The Fleet and Joint Force face a complex global security environment marked by the re-emergence of long-term, strategic competition between states, and evolving threats from non-state actors. The complexity of challenges created by our competitors and adversaries, coupled with the rapid pace of technological advancements, demands a cadre of judge advocates capable of integrated national security law and policy advice across the full range of military activities – conventional and unconventional, kinetic and non-kinetic, overt and clandestine.
