Mandatory military service

What do you think? Folks in Scandinavia are just crazy about it, I hear.

Mandatory military service has the effect that it decreases risks for military coups since a military without professional grunts is a lot less powerful (politcally). Its cheaper than having lax gun laws, plus it increases population fitness, decreasing population sickness and health care costs. Its not viable for the country who wants to send troops to foreign soils though.
