Eligibility notes
What 13F candidates should check.
- The current Army MOS 13F specification lists GT 87 as the qualifying score, effective August 2024. Older FA-score tables still visible in search results may be stale.
- GT is a job line score, not the overall AFQT percentile. Candidates still need to clear the Army AFQT floor before the MOS-specific GT requirement matters.
- The Army GT formula on this site is Verbal Expression plus Arithmetic Reasoning, so 13F prep should prioritize WK/PC and AR if your recruiter sheet uses the current GT standard.
- The same MOS specification also lists normal color vision, SECRET security eligibility, U.S. citizenship, and mandatory formal training for initial award of MOS 13F.
- The current GoArmy page says applicants enlist as Field Artillery Soldiers (13U), then receive a specific 13-series MOS assignment based on available Army opportunities and skills assessed during Basic Combat Training. Ask which job-selection terms will appear in the enlistment contract rather than assuming the 13U entry code guarantees 13F.
Which line score does 13F require?
13F requires GT of at least 87, per Army DA Pam 611-21 Chapter 10C — MOS 13F specification (PDF) (last verified 2026-08-06).
What is Army 13F called, and is it the same as "13 Fox"?
Yes — they are the same job. 13F is the Army Joint Fire Support Specialist MOS; "13 Fox" is how the code is said aloud, spelling the trailing "F" with the NATO phonetic alphabet (the Army usually shortens the NATO word "Foxtrot" to "Fox"). Whether you search "13F" or "13 Fox", the requirement on this page is the same: AFQT 31 and GT of at least 87.
What ASVAB score do you need for Army 13F?
For Army 13F Joint Fire Support Specialist, the current Army MOS specification lists GT 87, plus the Army AFQT floor of 31. GT is a line score, not the same thing as the AFQT percentile.
Does 13F use GT or Field Artillery (FA)?
The current Army 13F specification reviewed on 2026-08-06 lists GT 87. Older National Guard and third-party tables still show FA scores, so confirm the current line-score code on your recruiter score sheet or enlistment contract.
Which ASVAB subtests matter most for 13F?
If your 13F requirement is GT 87, focus on Verbal Expression and Arithmetic Reasoning. Verbal Expression comes from Word Knowledge and Paragraph Comprehension; Arithmetic Reasoning is its own ASVAB subtest.
What are the current Army 13F requirements besides the ASVAB?
The Army MOS specification also lists normal color vision, SECRET security eligibility, U.S. citizenship, and mandatory formal training. A recruiter confirms current openings and the full medical/background screen.
How long is Army 13F AIT?
GoArmy lists 10 weeks of 13F Advanced Individual Training after 10 weeks of Basic Combat Training. The Army National Guard gives the AIT duration as 10 weeks and four days at Fort Sill, Oklahoma. Confirm the dates on your current training reservation because schedules can change.
Can you enlist directly as Army 13F?
The current GoArmy page says applicants enlist as Field Artillery Soldiers (13U), then receive a specific 13-series MOS assignment based on available Army opportunities and skills assessed during Basic Combat Training. Confirm the job-selection language in your enlistment contract with a recruiter.
