Does being a 17c give you a leg up on the competition for getting an OCS slot?

To pile on, your enlisted MOS doesn't predetermine your Officer Branch during the accessions process. What the needs of the Army are at the moment you are looked at the end of OCS. It is all behind the curtain.

Does it seem reasonable that I could be a competitive candidate for OCS after day two years at my first duty station?

PFC (Join to see) You are using a criteria that is not really that relevant for the OCS application process. Time on station isn’t really a factor. It’s the “whole leader” concept, i.e. everything you are and have done in terms of leadership and Soldiering. As stated earlier, given where you are in your career, it will be much harder for you to be competitive than a Sergeant or Staff Sergeant who have held positions as NCOIC, team leader, squad leader, etc. This isn’t to say you aren’t competitive, I just don’t know you.

I think the best advice might be to get with the officer you respect the most (preferably captain or above). Learn what he/she does. Let them know that you are interested in this path and see if they will give advice, mentor ship, and support. I base this on my own experience. I didn’t consider OCS until the officers above me started to offer their support for me to go WO or Officer. Then I started doing the research as to what I wanted to do. But I had my battalion commander on down supporting me in this effort. If the officers above you do not think you should pursue a commission at this time, they will surely tell you and they will hopefully tell you what things you should concentrate on to get there. The probability of success of your application process is greatly increased if you have the support of your chain of command.
