Exercise Arcane Thunder Strengthens Interoperability

WIESBADEN, Germany - U.S. Army Europe and NATO allies will participate in Exercise Arcane Thunder 26, a multi-domain training event designed to strengthen interoperability and demonstrate the integration of advanced capabilities across the European theater.

The exercise will take place from April 6 to April 29, 2026, across locations in Germany, Poland, and the United States.

Arcane Thunder 26 validates the employment of Multi-Domain Company Teams, specialized formations integrating cyber, space, electronic warfare and conventional capabilities to create synchronized effects across domains.

"Arcane Thunder 26 marks a pivotal moment in our modernization efforts. We are qualifying Multi-Domain Company Teams to operate in today's complex security environment and across all domains." Says U.S. Army Col. Jeffery Pickler, commander, 2nd Multi-Domain Task Force. "Simultaneously, we are experimenting with cutting-edge technology and techniques, which will inform the force for years to come. Arcane Thunder 26 makes our Soldiers more lethal and ensures we and our Allies maintain a decisive advantage."

The exercise also supports the broader Sword 26 series, reinforcing NATO regional defense plans and improving the Alliance's ability to deter aggression and defend the Euro-Atlantic region.

Arcane Thunder 26 highlights the continued transformation of the U.S. Army as it operationalizes multi-domain capabilities and strengthens cooperation with allies and partners.
