JATEC and NATO assess the rapid-deployment capabilities of a NATO army corps during exercises

Representatives of the NATO–Ukraine Joint Analysis, Training and Education Centre (JATEC) participated in the final phase of the NATO exercise Loyal Dolos 2025, which assessed the combat capabilities of a NATO formation.

 Lessons learned from russia’s war against Ukraine were integrated into the scenario to prepare personnel for combat operations in a rapidly evolving operational environment. Ukrainian experts were directly engaged in NATO exercises of this kind for the first time.

 “Ukrainian JATEC experts’ involvement in LOYAL DOLOS 2025—one of NATO’s key training elements under Article 5 of the North Atlantic Treaty—has strategic significance for us, as it was the first time Ukraine took part in practising the Alliance’s collective security mechanisms,” noted Colonel Valerii Vyshnivskyi, Ukraine’s Senior National Representative to JATEC and Director for Program Implementation at the NATO–Ukraine Joint Centre.

 According to him, this contributed to the North Atlantic Council’s recognition of Ukraine as one of the most experienced participants in the regional security system and to a clearer understanding of the importance of cooperation with the Security and Defence Forces of Ukraine.

 Approximately 1,500 service members and civilian experts at various locations across Europe worked jointly to evaluate the capabilities of one of NATO’s rapid-deployment corps as an Alliance combat formation.

 The control group coordinating the exercise at the NATO Joint Force Training Centre (JFTC) in Bydgoszcz, Poland, ensured a comprehensive and realistic training environment.

 The LOYAL DOLOS exercises were designed to refine and assess the Alliance’s capacity to operate jointly across multiple domains concurrently.
