Mandatory army service has to be the most stupid thing around here, at least in countries who aren't likely to participate in any large-scale war in a conceivable future.
Regular soldiers are little more than cannon fodder for professionals.
So for a civilized country, regular army is pretty much pointless. I did my best not to waste almost a year doing that shit, as I find watching the paint dry more purposeful than learning how to use firearms and whatnot. Because even if I did learn how to use firearms, I probably wouldn't have the courage to actually go and fight in any serious war, so they'd have to shoot me as a deserter.
Anyway, I consider it a very wise decision from Roger, skipping the army like that. After all, wasn't Switzerland actually neutral in every war I can think of?
So what's the use for them having a regular army? They've got money, it's a better protection than any kind of army, anyway.
