MOS 2821 -- Technical Controller Marine

USMC computer networks
••• .mil

There are Marine Information Technology operators who specialize in the communication gear and electronics, but it is the MOS 2821’s job to ensure that the quality of the transmission/gear is being maintained.  Any data (satellite or standard wire or wireless network), the MOS 2821’s are the ones who make sure that the signal is as clean and operational.

The MOS 2821 use testing equipment and the knowledge you learn in MOS school. The Technical Controller (TechCon) will be doing this when deployed, and also in the field training.

When no operating communications networks, the TechCon Marine will be conducting inventories of gear, ensuring it is operational and doing limited technical inspection, preventative maintenance, and ensuring all equipment is accurately used, up to date and within standard.

The TechCon MOS 2821 school is in 29 Palms, CA. They will spend about three months in Basic Electronics School (BEC), and another five months in Technical Controller's Course TCC) for a total of around nine months in actual school. You may spend another 1-2 months in the Marines Awaiting Training (MAT) platoon when you first arrive on base.

TechCon Marines are few but highly trained.  There are not many of MOS 2821 created every year for the Fleet. Only about 50-60 finish MOS training every year. Many TechCons get out after 4 years because they are sought after in civilian business and can make 4-5 times the money of an enlisted Marine, especially if you deploy as a contractor for the Department of Defense and have a security clearance.

Communication Tech Marines have to be good communicators. Being able to communicate highly technical network issues and help non-technical people understand is critical to your career.

  Making sure people and your chain of command understand why links are not working clearly, how the network architecture is configured, and what your capabilities are will make your job much easier.

A Tech Controller MOS 2821 maintains networks, regardless of the gear that is within. A Tech Controller understands network architecture more so than any other MOS.  The gear may change at lightning speed, but the need for the Tech Controller to bring everything together is still there. Therefore, the Techcon Marine require high ASVAB scores and have to be intricate IT problem solvers.

When a new pieces of technological gear is purchased by the Marine Corps, the Marine Techcon typically tests and determines how to integrate it and makes recommendations for upgraded information technology.

Type of MOS : PMOS

Rank Range: Sgt to Pvc

Job Description: Technical controller Marines operate technical control equipment to locate faults or degradation in communication networks. They are in key positions to test transmission quality since most high-capacity communications circuits pass through tech control equipment. Typical duties include testing of circuits to ensure circuit quality is maintained, repair faults or degradation in communications networks, and maintain records on activation/deactivation of communications links. Technical controller Marines operate and maintain tech control equipment by performing tasks including equipment adjustments and replacing faulty components/parts.

Job Requirements:

(1) Must possess an EL score of 115 or higher

(2) Complete the Basic Electronics Course and Technical Controller Course.

(3) Marines must have 36 months obligated service remaining upon graduation from the Technical Controller Course. This obligated service must be obtained prior to execution of pes (DUINS) or PCA (DUINS) orders to the course.

(4) Must be eligible for a secret security clearance.

(5) Must have normal color vision.

(6) Must be a U.S. citizen.

Duties: For a complete listing of duties and tasks, refer to MCO 1510.44C, Individual Training Standards.
