Perhaps you should spend more time minding your beaches and not pronouncing on something YOU obviously know nothing about, civilian or not.
First of all, I believe MOS is an army term. I said I was in the Navy. But if I recall correctly, since you asked, I think the Army designation was 92Golf, maybe 97Golf, for a Navy CT. That could be the Marine classification. It has been 17 years since I was in.
Second, if you google cryptologic technician, you can get to: http://en.wikipedia.org/wiki/Cryptologic_technician
Which gives you:
Cryptologic Technician (CT) is a United States Navy enlisted rating or job specialty. The CT community performs a wide range of tasks in support of the national intelligence effort, with an emphasis on cryptology and signal intelligence related products.
Most CT personnel are required to obtain and maintain security clearances. Due to the highly classified work environment, it is not always possible to share resources with other commands. Almost every detail surrounding the CT world from administration to operations to repair requires dedicated technicians with appropriate security clearances (this accounts for the many branches of the CT rating, i.e. CTA, CTI, CTM, CTN, CTR, CTT). The contribution of an individual CT will depend upon the branch or career area.
Members of the CT community enjoy a wide range of career and training options. Once trained, a CT might serve ashore, afloat or in a airborne capacity. (It is rare, but some have earned all three, i.e. dolphins, wings and swords over the course of a career.) A CT can expect overseas assignments of lengthy duration.
So, pathetically speaking, it appears you qualify. Great job analyzing someone you've never met, nor know anything about. You qualify to be On The Internet. Your button saying so is in the mail.
