Timeline0-4 Years
PositionsCannoneer, Ammo Bearer, Driver
SchoolsAirborne, Air Assault
Pay$24K-$36K/yr
BonusUp to $40K (initial)

Junior enlisted Field Artillery Soldiers begin as cannoneers on a howitzer section, ammunition bearers, or vehicle drivers. Promotion to SPC/E-4 typically occurs within 2-3 years and brings increased responsibility as a gunner or assistant section chief.

This is the time to master the fundamentals of gunnery, pursue additional schools, and build the foundation for NCO leadership. Strong performance on section certifications and live-fire exercises sets the stage for competitive promotion.

  • PVT (E-1) to PV2 (E-2): 6 months — Cannoneer, basic crew duties
  • PFC (E-3): 12 months TIS — Proficient crew member, weapons qualification expert
  • SPC (E-4): 24 months TIS — Gunner or assistant section chief, mentor to new arrivals
  • Pursue Airborne, Air Assault, or Ranger School early
  • Master section certification and live-fire gunnery tables
  • Build PT score for competitive promotion and school selection

KeyNCOER performance

The NCO corps is the backbone of Field Artillery. Sergeants (E-5) serve as section chiefs or FDC NCOs, while Staff Sergeants (E-6) lead at the platoon and battery level. This is where artillery leaders are forged — directly responsible for crew training, gunnery qualification, and fire mission execution.

Completion of BLC (Basic Leader Course) is required for E-5, and ALC (Advanced Leader Course) for E-6. The FA Master Gunner course is the premier technical qualification for artillery NCOs and significantly improves promotion potential.

  • SGT (E-5): Section Chief — leads a howitzer section through all gunnery tables
  • SSG (E-6): Platoon Sergeant or Chief of Firing Battery — responsible for all section training
  • BLC required for promotion to SGT, ALC for SSG
  • FA Master Gunner course is the gold standard for technical expertise
  • Pursue JFO certification, Ranger School, or drill sergeant duty
  • Strong NCOER evaluations are critical for competitive promotion

Timeline10-30 Years
PositionsSmoke, 1SG, CSM
SchoolsSLC, USASMA
Pay$52K-$90K+/yr
SelectionBoard-selected

Senior NCOs represent the most experienced and capable leaders in Field Artillery. Sergeants First Class (E-7) serve as "Smoke" (Chief of Firing Battery) or Operations NCOs, Master Sergeants/First Sergeants (E-8) lead at battery level, and Sergeants Major/Command Sergeants Major (E-9) serve at battalion, brigade, and higher.

These positions are highly competitive and board-selected. A record of successful gunnery qualifications, advanced school completion (especially FA Master Gunner), and consistent top-block evaluations are essential.

  • SFC (E-7): Chief of Firing Battery ("Smoke") — senior tactical NCO for the battery
  • MSG/1SG (E-8): Operations NCOIC or First Sergeant — battery-level senior enlisted
  • SGM/CSM (E-9): Command Sergeant Major — BN/BDE senior enlisted advisor
  • Senior Leader Course (SLC) required for E-7 promotion
  • Sergeants Major Academy for E-9 selection
  • Instructor and drill sergeant duty build competitive records
OCS
Officer Commissioning
PathOCS / Green-to-Gold
Duration12-16 Weeks (OCS)
LocationFort Moore, GA
Result2LT Commission
BonusBranch selection

Enlisted Field Artillery Soldiers with leadership potential and a bachelor's degree (or willingness to earn one) can pursue commissioning through Officer Candidate School (OCS) or the Green-to-Gold program. OCS is a 12-week intensive course at Fort Moore, while Green-to-Gold sends soldiers to college full-time with an ROTC scholarship.

Former enlisted artillerymen who commission as FA Officers bring invaluable tactical experience. Many of the Army's best fire support officers and battery commanders came up through the enlisted ranks, with deep knowledge of gunnery and fire direction operations.

  • OCS: 12-16 weeks at Fort Moore — rapid commissioning path
  • Green-to-Gold: 2-4 year college program with ROTC scholarship
  • Field Artillery Basic Officer Leader Course (FABOLC) follows commissioning
  • Ranger School highly encouraged for FA Officers
  • Prior enlisted experience is a massive advantage in battery leadership
  • Career progression: FDO → XO → BTY CDR → BN/BDE Staff → BN CDR

Common Questions
Training
Want to Call for Fire?

13F Fire Support Specialists operate on the front lines with maneuver units, calling for and adjusting indirect fire. Master the call-for-fire format, observer-target factors, and digital fire control to become an elite FIST member.

Gunnery
Struggling with Gunnery?

Gunnery tables are the measure of a cannon section. From dry-fire drills to live-fire qualification, master your crew duties, safety procedures, and fire commands. Repetition builds speed and accuracy under pressure.

Technical
Need AFATDS Skills?

AFATDS is the nerve center of fire direction. 13Js and FDC personnel must master mission processing, system configuration, and network operations. Hands-on time with the system is the fastest path to proficiency.

Schools
Eyeing JFO Certification?

Joint Fires Observer certification qualifies you to call for and control joint fires including CAS and naval gunfire. It's one of the most respected qualifications in the fires community and opens doors to joint assignments.

Career
How Do I Become a FIST?

Fire Support Teams (FISTs) are embedded with maneuver companies. Enlist as a 13F or volunteer for FIST duty as an NCO. Strong land navigation, communication skills, and infantry tactics knowledge are essential.

Promotion
How Fast Can I Promote?

Field Artillery promotion to E-5 averages 3-4 years. BLC completion, a strong NCOER, Master Gunner qualification, and additional schools like Airborne or Ranger dramatically accelerate the timeline.

The Cannoneer's Dedication

I am a Cannoneer.
I serve in the King of Battle,
the most lethal arm of the Army.
I deliver fires that shape the fight,
destroy the enemy, and protect the force.
My howitzer is my weapon,
my section is my team.

I will never fail my crew,
my battery, or my mission.
I train to standard, fire on call,
and answer every mission with steel.
I am the thunder of the battlefield,
feared by all who oppose us.

King of Battle!
