What this means
Official Army Chapter 10c PDF lists minimum GT 87; OPAT, training, clearance and other requirements remain separate.
The score listed above is the minimum line score threshold from the official Army MOS specification. Meeting this threshold does not guarantee enlistment — additional requirements such as OPAT physical testing, security clearance, medical screening, and training availability are evaluated separately by your recruiter. To see how GT 87 compares with the rest of the Army, read what counts as a good ASVAB score.
Which ASVAB subtests count toward 13M
13M is judged on one line score. The subtests listed below are the Army's nominal definition of each aptitude area from DA PAM 611-21, Military Occupational Classification and Structure, Table 10-1 (ASVAB aptitude area composites). The score actually printed on your report is computed on the 1997 scale as a weighted sum of seven standard scores (DMDC 2004, Table 2.7) and may give weight to subtests outside the nominal list; GT is the exception and equals AR + VE exactly. Use the line score on your report, or compute it from your standard scores.
VE (verbal: WK and PC) + AR
WK (Word Knowledge), PC (Paragraph Comprehension), AR (Arithmetic Reasoning).
If your score is below GT ≥ 87
Your ASVAB report lists every line score, so start by finding GT and noting the exact gap. A small gap in one composite is usually closed by improving the subtests that feed it, and each subtest counts toward several line scores at once.

A retest is subject to Army retest rules and timing; ask your recruiter before planning around one. Practice results here are raw scores and never convert into an official line score.
Field Artillery jobs ranked by ASVAB threshold
All 5 currently verified CMF 13 entries on this site, ordered by the lowest score that satisfies each rule. 13M sits at position 4: 0 jobs list a lower threshold and 0 list a higher one. Thresholds in different line scores are not directly comparable.
Other Army jobs judged on GT (General Technical)
Because these MOS share the GT line score with 13M, the same subtests decide your standing for all of them. Jobs at or below 13M's threshold are fallback options; jobs above it are what a higher GT unlocks.

Frequently asked questions
What ASVAB score do I need for 13M MLRS/HIMARS Crewmember?
The verified score threshold recorded for this MOS is GT ≥ 87. Other requirements such as OPAT, clearance, and training are separate.
Which ASVAB subtests count toward the GT score for 13M?
GT (General Technical) is nominally VE (verbal: WK and PC) + AR. The reported score is a weighted sum of seven standard scores on the 1997 scale, so subtests outside that list can also count. Compare the line score printed on your ASVAB report against GT ≥ 87, or compute it from your standard scores with the calculator.
Is AFQT enough to qualify for 13M?
No. AFQT is used for general enlistment qualification. 13M uses specific Army line scores (GT ≥ 87), and the line-score rule shown here is the verified threshold. These are composite scores calculated from ASVAB subtests and are different from your AFQT percentile.
Are there Field Artillery jobs with a lower ASVAB threshold than 13M?
No. 13M has the lowest entry threshold among the 5 currently verified CMF 13 entries on this site; 0 list a higher one.
Where does this 13M score requirement come from?
The verified threshold is recorded from the official Army MOS specification document. Initial award, Chapter 10c; score requirement verified in official Army PDF. Source checked on 2026-09-12.
