Plenty of countries manage to conspript pretty much everyone at a certain age. Train them and let them home without having a special problem with them. Now what is the US army doing during training/stateside service?
Israeli conscription is mandatory for adult citizens on or about their 18th birthday with a service obligation of 3 years for males and 2 years for females, but you can defer service until after completion of undergraduate education for 6 years as an officer.
Stories of abuse during draft service were so common in many countries that people normalized them.
