Eligibility notes

What 11C candidates should check.

  • 11C qualifies on the Army's Combat (CO) line score. DA Pam 611-21 Chapter 10C — the Army's own enlisted MOS specification — states for 11C: "Qualifying Scores. A minimum score of 77 in aptitude area CO." This page publishes that figure, read from the 2025-12-04 edition on 2026-08-16.
  • Correction (2026-08-16): this page previously published CO 87, the figure carried by widely-copied third-party recruiting tables. DA Pam 611-21 does list a CO 87 — but for 19Z, Armor Senior Sergeant, a different MOS. If a table told you your CO score was ten points short of 11C, check it against the Army specification linked below.
  • There is no ASVAB gap between 11B and 11C. DA Pam 611-21 Chapter 10C sets both at CO 77, which is consistent with the two being assigned under the same 11X infantry enlistment option.
  • The Combat (CO) score area is built from Verbal Expression, Auto and Shop Information, and Mechanical Comprehension — so AS and MC matter as much as WK/PC for an 11C target.
  • 11C is assigned under the 11X infantry enlistment option alongside 11B; the specific MOS may be set during or after OSUT based on Army needs. Line-score minimums are revised between editions of DA Pam 611-21, so confirm the current figure on your enlistment contract.

What is Army 11C called, and is it the same as "11 Charlie"?

Yes — they are the same job. 11C is the Army Indirect Fire Infantryman MOS; "11 Charlie" is how the code is said aloud, spelling the trailing "C" with the NATO phonetic alphabet. Whether you search "11C" or "11 Charlie", the requirement on this page is the same: AFQT 31 and CO of at least 77.

What ASVAB score do you need for 11C Indirect Fire Infantryman?

Is 11C harder to qualify for than 11B?

No. DA Pam 611-21 Chapter 10C sets both 11B Infantryman and 11C Indirect Fire Infantryman at CO 77, and both train at Fort Moore under the 11X infantry option. Third-party tables that list 11C at CO 87 are carrying the wrong number — 87 is the Army's CO minimum for 19Z, Armor Senior Sergeant.

What does an 11C mortarman do?

11C Soldiers crew and fire mortars — the infantry's organic indirect fire. They compute firing data, emplace the gun line, and deliver high-angle fires to support maneuvering rifle squads.
