This interpretive study examines how motivation to engage in the Swedish Home Guard changes among volunteers without prior military experience who discontinue their involvement during recruitment or basic training. Based on nine semi-structured interviews the study applies thematic analysis to understand motivation as a dynamic and relational process. Findings show that initial motivation is often strong and value driven, rooted in civic responsibility and a desire to contribute. However, motivation is gradually challenged through demanding training experiences, organizational ambiguity, limited feedback, and difficulties balancing engagement with everyday life. Withdrawal is typically experienced as a rational and meaningful decision rather than a sudden loss of motivation. Drawing on previous research and Battistelli’s motivational framework, the study highlights how different motivational dimensions are negotiated over time. Importantly, discontinuation does not necessarily imply reduced defence willingness or motivation, but rather reconfiguration of the commitment.
