Over the last few decades, most countries in Europe have abolished compulsory military service. But following Russia’s invasion of Ukraine, the debate around conscription has returned. Last year Latvia restarted mandatory military service for men between 18 and 27. And now other countries are expanding their policies on conscription and encouraging their allies to follow suit. Last month Denmark proposed extending mandatory military service to women.

BBC Europe correspondent Nick Beake explains why countries are bringing back conscription and how changing rules are affecting young people. We also hear from two young conscripts in Estonia . They describe their training and the mental toll it can take.
