The paper examines the role of Polish artillery in a multi-domain battlefield. It uses literature and doctrinal analysis to assess how integration across land, air, sea, space, cyber, and cognitive domains affects artillery effectiveness. Findings show that artillery is increasingly dependent on interoperability, information flow, and systemic resilience. The study highlights new threats and opportunities, including A2/AD development. It concludes that multi-domain integration, rather than firepower alone, determines future combat effectiveness.
