MOS 94E Radio & COMSEC Repairer Duty Descriptions

Major Duties: The radio and communications security (COMSEC) repairer performs or supervises direct and general support (DS/GS) level maintenance of radio receivers, transmitters, COM-SEC equipment, controlled cryptographic items (CCI), and other associated equipment. Duties for MOS 94E at each level of skill are:

Skill Level 1 MOSC 94E1O

The Air Traffic Control Equipment Repairer at Skill Level 1 (MOSC 94E1O) utilizes test, measurement, and diagnostic equipment (TMDE) to identify the cause and location of malfunctions, assess the extent of faults, and determine the maintenance category required. They are responsible for repairing systems, equipment, and subassemblies by adjusting, aligning, repairing, or replacing defective components, cryptographic items, or line replaceable units (LRU). The repairer conducts bench tests to ensure the operability of repaired equipment and ensures that emission security standards are met. Additionally, they evacuate damaged equipment and components to higher-level repair activities and perform preventive maintenance checks and services (PMCS) on tools, TMDE, vehicles, and power generators.

Skill Level 2 MOSC 94E2O

At Skill Level 2 (MOSC 94E2O), the Air Traffic Control Equipment Repairer performs complex and multi-failure tasks while providing technical and procedural assistance to subordinates. They conduct equipment tests to localize and diagnose the causes of malfunctions and exchange faulty equipment as needed. The repairer carries out difficult or complex repairs on defective components, subassemblies, and related cabling. They ensure that COMSEC/CCI repairs use National Security Agency (NSA) approved components. The repairer communicates equipment repair status, priorities, and the need for bench stock resupply to the shop supervisor. They also perform final or quality control inspections on repaired equipment and maintain control and accountability of CCI within the repair facility.

Skill Level 3 MOSC 94E3O

The Air Traffic Control Equipment Repairer at Skill Level 3 (MOSC 94E3O) assumes additional responsibilities such as establishing work schedules and repair priorities. They assign and supervise shop repair operations and personnel. The repairer provides technical information on repair functions and imparts knowledge of complex or special tasks to subordinates and supported units. They supervise quality control and/or final inspection of radio, cryptographic items, and related communications equipment. Ensuring compliance with Army and NSA COMSEC specifications and policies is also part of their role. The repairer develops standing operating procedures that are relevant to DS/GS shop operations and conducts technical and on-the-job training programs within units.

Physical demands rating and qualifications for initial award of MOS. The radio and communications security (COMSEC) repairer must possess the following qualifications:

(1) Physical Demands Rating: heavy

(2) Physical Profile: 111221

(3) Normal color vision.

(4) Minimum score of 110 in aptitude area EL.

(6) Successful completion of one year of high school algebra and general science.

(7) A U.S citizen.

(8) Formal training (completion of MOS 94E Course conducted under the auspices of the U.S. Army Ordnance Missile and Munitions School) mandatory; or waiver may be granted by Commandant, USAOMMCS, Redstone Arsenal, AL 35897-6090.

(9) Must be certified as COMSEC equipment repairer contained in AR 25-12.

MOS 94E was known as 35E before fiscal year 2006.

The major duties, physical demands, physical profile, and skill levels were obtained from Army Pamphlet 611-21.
