A Marine Corps Signals Intelligence (SIGINT) Analyst is a crucially important part of the Marine Corps' strategic planning operations, and it requires people who can focus for long periods of time and can distinguish valid intel from chatter.

The Marine Corps considers this job a necessary military occupational specialty (NMOS), which means it has a prerequisite primary MOS as well as specific training or skills. It's open to Marines between the ranks of master gunnery sergeant and corporal.

What Is a SIGINT USMC Analyst?

In the Marine Corps, just like in other branches of the U.S. armed services, Signals Intelligence (SIGINT) Analysts coordinate and analyze strategic and tactical intelligence. They listen to radio and other broadcasts to determine enemy positions and figure out when and where high-profile targets may be located.

The Marines categorize this job as MOS 2629.

Duties of Marine Corps Signals Intelligence Analysts

These Marines listen to intercepted messages and work to identify the valid intelligence from the noise. They help place and camouflage surveillance equipment and make sure all the equipment is working as intended.

Signals Intelligence Analysts are responsible for all facets of SIGINT analysis. They supervise communications security operations; develop and maintain records on technical aspects of target emitters; and develop and maintain communications order of battle files, situation maps, and other related SIGINT files.

While this may sound like a job with a lot of high-tech spy responsibilities, it does involve plenty of difficult, tedious work. Analysts prepare and issue a variety of reports: intelligence reports, technical reports, summaries, and the like. They may need to attend and address senior officers at SIGINT briefings.

Qualifying for MOS 2629

You need a score of 100 or higher on the general technical (GT) segment of the Armed Services Vocational Aptitude Battery (ASVAB) tests.

This MOS is typically assigned to Marines who already hold MOS 2621 (Special Communications Collection Analyst), MOS 267X (Cryptologic Linguist), or MOS 2631 (Electronic Intelligence Intercept Operator/Analyst).

As part of the preparation for this MOS, you need to complete the Marine Analysis and Reporting Course at the Marine Detachment at Goodfellow Air Force Base in San Angelo, Texas. As part of the course, you will learn the details of signals intelligence gathering and analysis.

If you are interested in working as a SIGINT Analyst, you will need to qualify for a top-secret security clearance from the Department of Defense. You should already have received this clearance for your prior MOS, but if more than five years have passed, you may be subject to re-investigation to re-qualify. This will involve fingerprinting and another set of background checks of finances and character.

You also must be eligible for access to Sensitive Compartmented Information (SCI) based on a Single Scope Background Investigation (SSBI). Again, this will depend on when your prior investigation was conducted, and you may need to undergo this process again.
