There's no reason as to why able men shouldn't be obliged to serve their country in times of warfare crisis and/or be prepared for hypothetical wartime. Not only that, but it provides a gargantuan amount of benefits, such as: physical conditioning, mental toughening and a chance to help promote equality between young and old men alike. There's so many immature, feeble-minded, snobbish pretty boys nowadays who need to be kicked in the ass and grow the hell up, and I believe that compulsory military service/temporary military training should be implemented as soon as possible.
