Which qualification is necessary to operate the M119A3?

To operate the M119A3 howitzer, completing Advanced Individual Training (AIT) is essential. AIT is where soldiers receive specialized training in their chosen Military Occupational Specialty (MOS), which for cannon crewmembers is typically 13B. During AIT, soldiers learn the necessary skills to operate artillery systems, including the M119A3. This training covers the technical aspects of the equipment, safety procedures, and operational tactics required for effective artillery support.

The other options represent different training paths that serve other purposes. Basic Combat Training provides foundational military skills and discipline but does not include the specific training on artillery systems. Air Assault School and Ranger School focus on different capabilities and skill sets that deal primarily with airborne operations and leadership in combat situations, respectively, and do not qualify a soldier to operate the M119A3. Thus, Advanced Individual Training is the critical qualification required for operating this specific piece of artillery.
