About Arcane Thunder

Arcane Thunder 26 highlights the U.S. Army’s continued refining multi-domain operations and demonstrates how U.S. forces operate alongside NATO Allies and partners to deter adversaries across Europe. The exercise validates the employment and qualification of Multi-Domain Company Teams (MDCTs), integrating cyber, space, electronic warfare, and conventional capabilities to create synchronized multi-domain effects.

Arcane Thunder 26 is a geographically distributed exercise conducted across the United States, Germany, and Poland that links sensors and shooters across domains to enable rapid decision-making and precision effects. The exercise supports NATO regional defense plans and reinforces the Eastern Flank Deterrence Initiative (EFDI), demonstrating the Alliance’s ability to deter aggression and defend the Euro-Atlantic region.

Through Arcane Thunder 26, U.S. and Allied forces rehearse the integration of kinetic and non-kinetic capabilities to penetrate and disintegrate adversary anti-access/area denial (A2/AD) systems, enabling freedom of maneuver for the joint force and strengthening NATO’s deterrence posture.
