GAMECHANGER: A case study of AI innovation at the Department of Defense

Brookings

2025.12.03

Taking advantage of rapid advances in artificial intelligence (AI) is an active and ongoing priority for the United States Department of Defense (DOD). While attention has largely focused on AI’s role in warfighting systems, the Pentagon’s vast business operations―finance, procurement, internet technology (IT), health care, supply chain management, and more―are equally critical. Indeed, the DOD is the country’s largest employer, provides health care to 9.4 million people, owns and/or manages more than 700,000 facilities worldwide, is fiduciary of almost 1 trillion taxpayer dollars (and growing), and is charged with buying and firing weapons in ways that are legal, ethical, and effective. Whether and how well the DOD uses AI to enhance the voluminous set of workflows required to dispatch these “back room” and “boardroom” duties, therefore, has implications that extend well beyond the battlefield.

This report is a retrospective examination of one such effort. It offers a snapshot in time, focusing on the development of GAMECHANGER, a large language model-based application. It was designed to enhance access to the large volume of government authorities, directives, and policies that govern the DOD’s administrative and military operations. GAMECHANGER was codeveloped in 2018 by the government in partnership with the private advanced technology company Booz Allen and implemented in 2020. It therefore predates the release of GPT-3, and the generative AI fervor triggered by its successor, ChatGPT.
