Apps at War: Army+, Reserve+ and the Rise of Digital Defence Governance in Ukraine
Ukraine’s effort to resist a larger opponent, while retaining democratic norms, has pushed digital defence governance to the centre of how the state mobilises people and manages military service. Two mobile applications, Army+ and Reserve+, reveal how digital tools can transform mobilisation and military administration by re-engineering core governance processes.
This research report – by Matthew B. Arnold, Viktoriia Roller and Khrystyna Zhyvogliad – draws on key informant interviews, legal analysis, and implementation reportage. It examines the policy problems the applications seek to address, assesses their contributions to national defence, and analyses which elements merit consideration by both NATO and EU allies.
This report was produced in partnership with the BRDO (Better Regulation Delivery Office), an NGO registered in Kyiv, Ukraine.
This paper is published as part of the Democratic Resilience in the New Age of War programme.
