Army Reserve and National Guard versus Regular Army

Forgive me for asking a stupid question, but why would anyone straight out of high school join the Army Reserve or the National Guard right now? Consider – if you want to serve in a combat zone, you would go ahead and sign up for the regular Army, as it increases your likelihood of a combat zone posting. On the other hand, if you specifically do not want to end up in a combat zone, well, the Army Reserve or the National Guard is not the right place for you either. One weekend a month, two weeks a year has gone by the wayside a while ago.
