What is MOS 0800?

MOS 0800 refers to the Military Occupational Specialty associated with Field Artillery. This specialty involves operations related to the deployment and utilization of field artillery units, which are critical for providing indirect fire support on the battlefield. Those trained in this MOS gain expertise in the various artillery systems, fire direction procedures, and the coordination of combat operations involving artillery units. As field artillery is essential for enhancing ground troops' combat effectiveness, personnel in this MOS play a vital role in supporting both offensive and defensive operations.

While infantry, logistics, and military police are also important specialties within the Marine Corps, they correspond to MOS codes distinct from 0800. Therefore, the designation of 0800 specifically identifies the field artillery specialization within the broader scope of military operations.
