Although the last few decades have witnessed a shift from conscription to all-volunteer forces in many European countries, recent changes in the European security environment have raised new concerns and prompted several countries to reconsider conscription. However, modern conscription systems have also had to adapt to changing societies and an increasing emphasis on individualistic and neoliberal values. This study aims to examine the various forms of military conscription and illuminate the continuing viability of the conscription model in six European countries: Estonia, Finland, Lithuania, Norway, Sweden, and Switzerland. Four of these countries have consistently maintained conscription (Estonia, Finland, Norway, and Switzerland), while Lithuania and Sweden have recently reinstated conscription. Although conscription systems differ among these countries, there is overall an increasing emphasis on conscript motivation and female participation. Three key aspects are identified to describe different conscription systems: the proportion of conscripted individuals in the birth cohort, motivation to serve, and the approach to female conscripts. Combining these aspects, the study identifies three types of conscription system in these six countries. This article demonstrates that conscription has evolved and adapted to changing societies and security situations instead of merely retaining its traditional form.
