> What do you do with a conscript who never wanted to be there and possibly fundamentally isn't suited to military life anyway gives up? Threaten them with legal action?

In some countries, you will get punished - get assigned bathroom cleaning for a week, get assigned lots of manual labor, or your whole squad gets punished which means they will have reason to 'motivate' you themselves. You can also go to military jail and get dishonorable discharged.

Basically, there is the carrot motivation method, and then there is the stick method.
