Each of the functional areas of the Marine Corps Field 08 require different areas of expertise and responsibility for training. The three areas work together as a team to make the weapon system work properly and with precision.  The following areas and their basic duties are listed below:

Firing battery includes moving, emplacing, loading, firing, protecting, and maintaining field artillery cannon weapons systems. The grunt work of operating the weapon systems are the firing battery responsibilities.

Field artillery operations involve moving, emplacing, operating, protecting, and maintaining equipment which acquires targets; provides, relates, and evaluates gun and target survey information, meteorological data, weapon system performance.  Integrating these factors into orders and communicating these orders to the firing battery is how the precision is created.

Field artillery observation and liaison responsibilities include checking and analyzing combat plans and communicating appropriate advice, planning and operating information.  Coordinating the fires of field artillery and naval guns with infantry and armor combat maneuvers requires constant updates and communication with both field commanders and Naval gunfire platforms.   Adjusting fire for battlefield targets in coordination with military commanders on the ground is the additional step to make artillery the deadly weapons system that it is.

Qualifications of Marine Corps Field Artillery

Qualifications for this Marine Corps position include:

  • Ability and learned skills to operate and maintain artillery equipment.
  • Basic technical and mathematical skills for computing, communicating and executing fire commands.
  • Ability and attitudes supporting life and close work with others in a field environment.

Entry-Level Jobs

Types of entry-level jobs include work as field artillery battery man or Cannoneer, radar operator, fire control man, meteorological man, and as a fire support man, spotting fires of artillery and naval gunfire.

Formal schooling or field skills training is provided to Marines entering the OccFld. Because field artillery is the primary supporting arm for Marine Infantry and Armor, most of its billets are in FMF ground organizations.

The Marine artilleryman finds most assignment opportunities similar to the wide variety of billets available to those in other combat and combat support fields at all staff levels of the division and in various free billets. Marines entering this OccFld receive MOS 0800, Basic Field Artillery Man, and under instruction and close supervision, perform the routine duties incident to the firing, operation, and maintenance of field artillery pieces and related equipment.

These Marines are trained for one of the MOSS in the field artillery OccFld and participate in routine functioning and tactical employment of the unit to which attached.
