wwwwwwwwwwww An Cosantóir July / August 2026 www.military.ie/magazine T he ability to communicate, share information and operate alongside international partners has become an essential requirement for modern military operations. Whether supporting United Nations peacekeeping or European Union missions, interoperability underpins operational success by enabling different nations to operate together in increasingly complex environments. Recognising this importance, the Defence Forces deployed three CIS Corps personnel, as observers, to the recent Coalition Warrior Interoperability Exercise (CWIX), at NATO Joint Force Training Centre, Bydgoszcz Poland. This provided prospects to identify opportunities for Irish participation from 2027 at one of the world's largest technical interoperability exercises. What is CWIX? CWIX is NATO's annual technical interoperability exercise. It brings together military communications specialists, engineers and software developers from NATO allies, Partnership for Peace Nations and approved industry partners to test national command, control and communications systems interoperability. Each year, thousands of participants attend the exercise to validate new technologies, assess interoperability against recognised standards and identify technical improvements before deployment on operations. As a Partnership for Peace Nation and an Affiliate C member within Federated Mission Networking (FMN), Ireland has the opportunity to participate in this collaborative environment. Participation allows the Defence Forces to test its own systems against internationally recognised standards and ensure compatibility with those of partner nations. Observing Today to Participate Tomorrow The Defence Forces observer delegation attended CWIX 2026 with a clear objective to understand how Ireland could participate effectively in future exercises. The delegation observed interoperability testing across a broad range of capability areas which included tactical applications, radio integration, Federated Mission Networking and Software Defined Radio (SDR) waveforms. More than 3,000 personnel representing over 25 nations participated in the exercise, making CWIX an invaluable opportunity to engage directly with military experts, capability developers and technical specialists. The visit also enabled Defence Forces personnel to engage with technical specialists from other military organisations, NATO agencies and approved industry partners. These discussions provided valuable insight into current interoperability challenges, emerging technological developments and practical approaches to capability development. 8 | BUILDING INTEROPERABILITY BUILDING INTEROPERABILITY FOR FUTURE OPERATIONS FOR FUTURE OPERATIONS ARTICLE BY COMDT COLM KAVANAGH
