13A vs 56A
Field Artillery, General (USA) vs Command and Unit Chaplain (USA)
The Army promised both of these were "critical to national defense." The Army has a very generous definition of that phrase.
When a 13A and a 56A both hit terminal leave in the same month, the job market receives two very different veterans. The 13A brings: the civilian market for FA officers is less direct than engineer or medical — project management, leadership development, and operations management are the primary translation lanes. The 56A arrives with: post-Army civilian ministry, counseling, and hospital chaplaincy are the primary pathways. Both earned their DD-214. The civilian world values them at different exchange rates. A recruiting station near you is currently presenting both of these as "the best-kept secret in the military."

The pitch versus what people who actually did the job report back.
“Command the Army's most powerful indirect fire systems. Field Artillery officers deliver fires that shape the battlefield from distance, with technical precision and tactical impact.”
Field Artillery officers live in a world of GRIDs, call for fire, fire missions, and the continuous tension between fires integration and maneuver deconfliction. Your first years will involve learning the fire direction process deeply enough to supervise it — AFATDS, AFATDS troubleshooting, AFATDS freezing at the worst moment. Battery command is genuinely the best part of the FA career for most officers — you own a capability that maneuver commanders actually need and your soldiers are doing skilled, demanding technical work. The staff years as a fires officer involve writing OPORD fire support annexes and sitting in targeting meetings. The FA branch has watched the rocket artillery renaissance with satisfaction as HIMARS became the most consequential ground system in Ukraine. The civilian market for FA officers is less direct than engineer or medical — project management, leadership development, and operations management are the primary translation lanes.
“Serve soldiers' spiritual needs and provide pastoral care across the Army. A unique ministry career that provides counseling, religious support, and moral leadership throughout the force.”
The Chaplaincy is one of the few places in the Army where the mission is explicitly the care of human beings — you are there for the soldier who is struggling, the family at the notification, the unit that just lost someone. The work is real and important and different from every other officer specialty in that you carry a dual identity as both commissioned officer and ordained religious professional, and the tension between those identities in a pluralistic institution requires constant navigation. You are required by law and conscience to support religious practices you may not share, which is either a profound exercise in religious tolerance or a daily challenge depending on your tradition. The confidentiality of pastoral care creates a unique trust relationship with soldiers that few other officers get to experience. The burnout rate in the Chaplaincy is significant — carrying the spiritual and emotional weight of units under stress is not a theoretical burden. Post-Army civilian ministry, counseling, and hospital chaplaincy are the primary pathways.
The Real Life
Same dimensions, side by side. 13A on the left, 56A on the right.
Leading fire direction operations, planning fires in support of maneuver commanders, and coordinating all indirect fire assets. As a platoon leader: responsible for a firing battery. As a fire support officer (FSO): embedded with a maneuver battalion coordinating fires. The job is intellectually demanding — translating a commander's intent into effective fire plans.
Providing religious support, counseling, and spiritual care to soldiers and families. Conducting worship services, performing religious rites and ceremonies, and advising commanders on morale, welfare, and ethical issues. Chaplains are noncombatants under the Geneva Convention — they carry no weapon. The role blends pastoral care with military leadership.
Field Artillery Basic Officer Leader Course (FABOLC) at Fort Sill (OK) is about 18 weeks. Covers gunnery, fire support planning, targeting methodology, and digital fire control systems. The math and technology behind modern fire support are more sophisticated than most people realize.
Chaplain Basic Officer Leader Course (CHBOLC) at Fort Jackson (SC) is about 12 weeks. Covers military ministry, counseling, pastoral care, and chaplain operations. Entry requires ordination or endorsement from a recognized religious organization, a master's degree (typically MDiv), and demonstrated ministerial experience.
High. Field artillery officers are combat arms and expected to maintain high physical fitness. Field exercises involve extended time in tactical command posts and fire direction centers.
Moderate. Chaplains are expected to maintain PT standards and operate in field conditions. They accompany their units to the field and on deployment — everywhere the soldiers go, the chaplain goes.
Field artillery officer is a branch that operates in the shadow of infantry and armor but provides some of the most lethal capabilities on the battlefield. What the recruiter won't tell you: field artillery is a branch that many officers don't choose first but end up loving. The technical challenge of coordinating fires — multiple weapon systems, joint assets, timing, and effects — is genuinely intellectually stimulating. The downside: garrison artillery can feel like an endless cycle of gunnery certifications and maintenance, and the branch has an identity crisis in an era where close air support and precision munitions compete with traditional artillery. The fire support officer role (embedded with infantry or armor) is where most FA officers find the most fulfillment. The civilian translation requires work — "I coordinated lethal fires" doesn't land in a job interview. Translate it to planning, coordination, and decision-making under time pressure.
Military chaplain is one of the most unique and demanding officer roles in the Army. You are simultaneously a religious leader, a counselor, a commander's advisor, and a moral compass for your unit. What the recruiter won't tell you: the emotional burden is enormous. You counsel soldiers through suicides, sexual assaults, combat trauma, family crises, and moral injuries — and you do it while maintaining confidentiality, which means you carry that weight alone. The requirement to support all faiths equally can create tension with your own religious convictions, and navigating that tension requires maturity and flexibility. The chaplain community is smaller and more tight-knit than most branches. Post-military, many chaplains continue in civilian ministry, hospital chaplaincy, or counseling. The pastoral and counseling experience gained in the military is unmatched in its intensity and breadth.
