How likely would it be for me to reclassify to 17C?

11B is not at all over strength, it's under strength acroos the Army for E4 and E5.
It's easy to switch, as long as you pas the test and are accepted.

Be honest, the infantry wasn't what you hoped and now you want to go play with computers. There's more to the Army/military than the job you do, there's also the part of honoring your commitments and putting up with all the bs that comes with being a soldier.

It is likely you could reclass, back when I was in there where lists of soldiers wanting to trade MOS with other soldiers (these were posted by company HQ on the wall) but it has to go up the chain and mostly likely will be turned down since its your first enlistment. Why? Well because the Army paid money to train you as an 11B and they want a return on their investment. Plus, how long is 17C training? Is there enough time remaining on your contract to go through training and enough time for the Army to get a return on their investment for your reclass?

If you don't mind it as you say, then just see it through to the end and learn all you can about physical security. You can combine that with your cyber skill training later on and have a more well rounded perspective of security convergence... since the two do intersect and affect each other.

There are plenty of prior 11B’s hanging around the 17C world. Put it this way, at the time I applied I had about two years of college in towards a computer science degree, no certifications, and a little experience in IT before the Army and I got picked up. Put your packet in.

Other than that, the school is in two locations and a combined 12 months between Pensacola and Fort Gordon. Is a sweet career field if you’re looking at saying in and getting out.
