I think the draft qualifies as "exigent conditions" in which some rights and ethics get suspended in favour of the "greater good", or if you mean mandatory military service, I think most western nations stopped having that. Do you have something more mundane in mind?

[edit] To answer your question: yes, there are only 66 countries with mandatory military service. Among the Western democracies there are the Nordics, Estonia, Austria and Greece. From here: https://worldpopulationreview.com/country-rankings/countries...

I don't see how "greater good" justification is any different between my example and the topic.

The ethical system on which modern Western societies are built allows for body autonomy, while at the same time covers some corner cases: war, pandemic, etc. The fact that there are exceptions doesn't somehow invalidate the basics.
