U.S. Strategic Command, and the under secretary of Defense for intelligence and security, convened a digital table-top exercise to prototype cross-combatant command collaboration using AI-enabled early warning alerts of peer-level threat movements. GIDE 2 was held in March 2021. GIDE 2 expanded participation to include all combatant commands and the JAIC. The goals of the experiment were to gain a common understanding and picture of the threat for each of the combatant commanders; obtain earlier indications of adversary actions through artificial intelligence and machine-learning tools; and conduct cross-combatant command coordination on response actions, thereby obtaining faster decisions and ultimately, improving deterrence. GIDE 2 incorporated “live-fly” events that provided additional input into the experiment which demonstrated not only increased global integration and cross-combatant command collaboration, it also introduced machine-enabled response options and links to live service-level data sets.
