It is presumed that there are some universal motives encouraging young people to either pursue or avoid military service, alongside other, more country-specific motives. This chapter aims to explore the motivation of youth to complete military conscription at the beginning of the twenty-first century. The main research questions are the following: How much are young people motivated to complete the conscription in the army? What determines the motivation of young people to complete military service? Why are some volunteers reluctant to join the army? An international comparative analysis of empirical data collected from six European countries has been conducted. The analysis is based on responses to the standard questionnaire question: How would you rate your motivation for conscription training at the beginning of the service? The study considers the attitudes of respondents from NATO and non-NATO member countries, countries with different conscription systems, as well as socio-demographic characteristics and personal values. In most cases, conscripts from Sweden and Norway demonstrate the highest motivation to attend conscription training, while conscripts from Switzerland and Estonia exhibit the lowest motivation. Finland and Lithuania are positioned in the medium range. Notably, Lithuania shows a higher variation in attitudes compared to all other countries.
