They really don't, most of my generation and their parents do everything they can to avoid it, but that aside:

I am all fine with serving my country, I would love to go back for e.g. 2 month per year or biannual to teach what I have gained to the next generation at a high school or university whatever even village schools.

The problem is military is not the one I could be the most useful, apart from the ethical questions. And they don't give you a choice about how you serve your country.
