Scout

I am a 19D - Cav Scout (SSG)... What we do as opposed to infantry is a matter of what unit your assigned. The Army is in the process of moving to a "lighter force" which means armor, cav and infantry units will be expected to be integrated a lot more than their current status...
19D will land you Ranger, Airborne, AAssault and Sniper when your ready... What has not been mentioned in this post is available billets. No - your not going to get any of these schools promised, it will depend upon the billets available to your initial unit. 19D's always have billets available, and your basic land nav skills out of AIT will be more than sufficient to qual for either Sniper or Ranger. However - b/f you go dreaming - I advise you take it step by step, master your IET and your skill levels 1&2 b/f moving on, don't worry if your not sure what I am talking about - it will all come in due time. Your going to have a ton of information dumped on you as is - that is why most advanced schools require NCO status or Corporal in a "leadership role."
