Ukraine Shows AI Changing How Coalitions Fight

Courtney Stewart , Carl Janz

Coalition warfare has always been messy. Different procedures, systems, standards, doctrines, and operational caveats complicate and slow coordination at every level of conflict. AI may finally cut through that dynamic to become the connective tissue that makes multinational forces more cohesive and coherent. AI’s role in assisting coalition forces adapt to the modern battlefield was a key topic of the ‘Revolutions in military technology: lessons from Ukraine’ panel session at ASPI’s December 2025 Sydney Dialogue.

Marco Criscuolo, NATO’s acting deputy assistant secretary general and director for strategy and policy with the Cyber and Digital Transformation Division, likened managing NATO’s multi-domain operations to solving a three-pronged problem. On one axis lie the ‘five operational domains’, on another the ‘strategic, tactical, and operational levels’ and finally ‘the five classification domains, from NATO unclassified up to top secret’. The challenge of making real-time decisions is complicated not only by coordinating these domains, but also by the presence of multiple militaries. According to Criscuolo, it ‘is not possible’ to do so effectively without AI capable of quickly processing mass data points.
