Abstract

The New Force Model (NFM) represents a fundamental shift in NATO’s defence posture. This strategy is designed to enhance rapid deployment, deterrence, and interoperability in response to the current volatile geopolitical context characterised by evolving security threats. This study examines the NFM’s origins, structural evolution, and operational implications, particularly considering Russia’s aggression and the new dimensions of hybrid warfare. A key element of this transformation is the Allied Reaction Force (ARF), whose multi-domain capabilities are currently being assessed through Steadfast Dart 2025 (STDT25), NATO’s largest military exercise of the year. The findings highlight progress in force readiness while underscoring persistent challenges, including logistical coordination and multinational integration. As NATO adapts to modern warfare, refining the NFM will be essential to maintaining credible deterrence and collective defence.
