A Fire Support Specialist is a member of the Army's field artillery team. Artillery are weapons that fire large ammunition, rockets or missiles to support infantry and tank units in combat. 

The Fire Support Specialist, which is military occupational specialty (MOS) 13F, is primarily responsible for leading, supervising or serving in intelligence activities such as target processing for artillery units and maneuver brigades.

Duties Performed by MOS 13F

Soldiers in this job are critical to on-the-field combat operations. They're responsible for operating radio wire communications and speech security equipment. This might include encoding and decoding messages, as well as establishing and maintaining equipment. They'll help train subordinates in support procedures and tactics, and lead and train the forward observer team in combat operations. 

There's a fair amount of what might seem like clerical work involved too, including preparing fire support situation plans and maps, status charts, capability overlays, target lists and other coordinating documents. 

MOS 13F also assists in operating equipment like laser range finders, target designation and night observation devices. These soldiers are also responsible for maintenance on section vehicles and generators and participate in organizational maintenance of equipment.


In combat situations, MOS 13F soldiers will prepare observer target lists and assist in formulating offensive and defensive fire support plans. They'll also request and adjust field artillery, mortar, and naval gunfire. These soldiers may be called upon for suppressive and screening fire, selecting observation posts, orienting maps and preparing terrain sketches and diagrams.


Qualifying for MOS 13F

To qualify for MOS 13F, you'll need an Armed Services Vocational Aptitude Battery (ASVAB) test score of 93 in the Field Artillery (FA) aptitude area. The subtests for this area include arithmetic reasoning (AR), coding speed (CS), mathematics knowledge (MK) and mechanical comprehension (MC). 

You'll also need to be able to qualify for either a confidential or secret security clearance, which will involve an investigation into your character and conduct. The investigation will look at any criminal record, your finances and overall stability to determine if you're eligible to have access to national security information. 

Normal color vision (no colorblindness) is required, and soldiers in this job must be U.S. citizens.

Training for Army MOS 13F

Job training for a fire support specialist requires 10 weeks of Basic Combat Training and six weeks of Advanced Individual Training with on-the-job instructions. Part of this time is spent in the classroom and part in the field under simulated combat conditions.

Some of the skills you'll learn in this MOS include ammunition techniques, operating gun, missile and rocket systems, and artillery tactics, techniques, and procedures
