68C is a good MOS, the drawback is its slow/low promotion rates. In fact, most 68 series MOS have low rates of promotion. But, if you're passionate about it, then go for it. You'd go to JBSA for classroom AIT, then a 1 year long OJT. That is, if that's how they're still doing that for the Charlie program.
I retired from the Army Nurse Corps and have always been impressed with our 68C LVNs. They should be warrants but that is another discussion. Great stepping stone especially if you want AECP and RN. Do everything you can do to avoid assignment in a CSH or whatever they call field hospitals at the time you graduate. You rarely take care of patients in those units. You rarely do patient care past E5 and if you like direct patient care then you need to be knocking out pre-reqs right now for the nursing school of your choice. I personally feel LVN-RN-NP is a better track that IPAP. IPAP I believe you need a bachelors to go into it, AECP about half that.
I'm not for reclassing, but I'm definitely biased. Looking at the scant data provided, don't judge the job on your 1st enlistment -- Don't know your situation, but not all SIGINT assignments are equal -- tactical SIGINT is vastly different than strategic. I've experienced all levels from muddy boots to operational to strategic -- all offer their unique challenges and rewards. I will also add that post Army careers are abundant with the skillset/clearance you have. That said, if you've taken stock of your situation and made the hard assessment to move on, Good Luck!
