Smith.... good follow up question
No you do not. I've been enlisted my whole career. I would stay a squad leader for as long as I can if they let me. Most of the officers I worked with and respected were all enlisted before commissioning. Depending on what you want to do... be the chief or the indian... the jobs are completely different. Most of the MI officers I worked with were staffers in a typical army unit... attending meetings, powerpoint rangers, briefers, or the S2. I wouldn't discount going the enlisted side. I may be a little biased. Talk to an enlisted active duty soldier (hopefully not a douche) in the branch you want to join (ie. Infantry?) that can tell you about their own experiences as the backbone of the Army.
What are your expectations as your daily duties in the branch you're interested in, if you were to pursue going the officer or enlisted side? Maybe going officer is more suitable for you... or maybe enlisted is the way to go.

You should consider the enlisted side, only if you are willing to work for a living.
