You will enjoy it a hell of a lot more than INF. First position is typically Fire Support and will be detached to a line unit. You'll spend your time playing infantry or armor as a fire support guy. I spent most of my first year with a Tank Company - lots of fun; crazy bunch of dudes. Then you'll move up to Fire Direction with a gun battery then Platoon leader. Sort of inverse to most line units; however, as a young LT you are responsible for firing planning and working hand-in-hand with the line unit CO. My CO was great and understood artillery fires; however, a lot of line unit CO's don't know the first thing about the use of artillery.
With that aside, Fort Sill sucks! Worst 6 months of my life at OBC. If you like nature, hiking, hunting, etc., it's a great place to be stationed;however, the night life has much to be desired. Plan on spending weekends in OKC or (and yes, it's a step up from Sill) Wichita Falls.
Overall, I think you'll enjoy being a Redleg. Not sure how the assess anymore, but you can go heavy or light artillery. I spent my time heavy, but knew a bunch of guys that went light and loved it. OBC focuses on light - CFF, fire direction, etc. You'll find a bunch of Aggies as both students and instructors. In my class we had 3 Aggie instructors and 5 Aggie students (2 Army and 3 Marine).
