Interesting question.
I went in 11X with the guaranteed Airborne option. Decided not to go directly to OCS from basic training (8 month wait, then would lose my airborne slot), but volunteered for Ranger Btn in jump school.
Never made it to Ranger Btn (have shoulders that dislocate if pulled from just the right angle, which prevent me from doing pull-ups. Even when busting my a** in holdover and getting to the point where I could do 8x 200lb lat pulldowns and only weighed 171 lbs.
Only thing I ever failed at...) so I went overseas instead. Turned down another OCS slot after arriving in Germany(would have had to stay in longer), then decided not to take "green to gold" when I ETS'd.
My experience (8 years ago) is that if you've got some college under your belt and you tested well (98% for me) you can find an OCS slot without too much difficulty. The enlisted experience sure seems a *lot* different than the commissioned experience though.
It seemed like we learned to fight, and the officers learned how to lead (whether they learned well or not is a different question). I saw two officers while I was in that I admired: one was a major at 3d Ranger Btn, the other was a 1st Lt in the Armored Btn I got assigned to (2/67 AR). In both cases, the officers were enlisted first (in the latter case, was 11B E-6 who used to teach at SEAR school...)
Want to go straight into en elite unit? There'll be a ton of competition. Want to go to Ranger school? My understanding was that infantry officers are required to pass ranger school within a certain period of time. I disn't see many infantry officers (I was 11C, and was plagued by a series of armored officers.
) but I never met a ranger school grad I was uncomfortable following.
FWIW. On the Army experience? Glad I did it. Loved the job, hated the organization. I'll keep my gripes to myself though, for fear of offending someone here.
Watch out though -- we used to harrass the hell out of those OCS guys (line up 5m apart and each ask "excuse me, do you have the time?" Funny watching the candidates in their shiny hats stop from double-timing, go to attention, then parade rest, then answer the question, go to attention again, double-time...
ROTC is surely less hectic. Besides, that way you won't wake up the airborne class next-door with your 2AM PT.
