NCOER Bullets for 91-Series Mechanics and Maintainers

SSG Alvarez runs the maintenance section for a company with 74 vehicles on the books. This rating period the company's fully mission capable (FMC) rate went from 71% to 93%. She traced a transmission overheating fault that two quarters of PMCS had written up as separate problems, and she got three new mechanics signed off on their skill level 1 tasks. Her draft bullet: "supervised maintenance operations and ensured vehicles were mission ready."

Any motor sergeant in the Army could sign that sentence. It leaves out the fleet, the fix, and the three Soldiers, which is to say the whole rating period.

Maintainers have a particular problem on the NCOER. When you do the job well, nothing happens. The convoy doesn't break down and the deadline list stays short. That is hard to write about, so 91-series NCOs fall back on task verbs like "repaired," "inspected," and "maintained." This post works through each block with weak and strong examples. The people and numbers in the examples are made up, so swap in your own. For the general approach to every block, see NCOER bullet examples by box. For the same exercise in a commo shop, see NCOER bullets for 25-series Signal Soldiers.

What the form asks for

The NCOER comes in three versions: DA Form 2166-9-1 for SGT, 2166-9-2 for SSG through 1SG/MSG, and 2166-9-3 for CSM/SGM. Part IV holds six blocks: Character, Presence, Intellect, Leads, Develops, and Achieves. After them comes the rater's overall performance assessment. The rater writes bullets on the SGT and SSG-through-MSG forms. On the CSM/SGM form the rater writes narrative instead. The senior rater writes narrative on all three.

DA PAM 623-3 (12 February 2025) sets the bullet rules. You need at least one bullet in every block. A bullet runs two lines at most, and one line is better. Each bullet starts with a lowercase "o" and then a past-tense action verb or "his" or "her." Each example gets used once, so you have to pick the block where a story fits best.

The box checks differ by grade. On the SGT form the rater marks each block "met standard" or "did not meet standard." The SSG-through-MSG form adds "exceeded standard" and "far exceeded standard," which DA PAM 623-3 describes as performance typically seen in the upper third of NCOs in the same grade. Your bullets have to back up whichever box gets checked.

The February 2025 revisions of AR 623-3 and DA PAM 623-3 removed diversity, equity, and inclusion language to comply with Executive Order 14151. The Character block still requires a comment on how the NCO promoted dignity and respect and supported the SHARP program.

Where maintainers find their numbers

You already track most of the evidence a rater needs:

• FMC rate at the start and end of the rating period
• The GCSS-Army equipment status report: what is deadlined, why, and for how long
• Scheduled services completed on time compared with overdue
• Results from Command Maintenance Discipline Program (CMDP) inspections and staff assistance visits
• Soldiers trained, signed off, licensed, or promoted out of your section

Most of it is a GCSS-Army report away, or on the slides you brief at the weekly maintenance meeting.

Achieves: readiness is the result

Maintainers undersell themselves most in this block. "Maintained vehicles" describes a task. An FMC rate is a result.

Weak:

o maintained company vehicles and equipment to Army standards; ensured all services were completed on time

Strong:

o raised company FMC rate from 71% to 93% across 74 vehicles in 8 months; cut deadlined vehicles from 19 to 4 before the unit's CTC rotation

Weak:

o performed diagnostics on vehicle faults and repaired them quickly

Strong:

o traced a recurring transmission overheating fault to a cooler line routing error; reworked it on 11 vehicles, ending 6 repeat work orders

The strong versions give a starting point, an end point, how many vehicles, and what changed for the unit. A rater can compare 71% to 93% with another NCO's numbers. Nobody can compare "quickly" with anything.

Leads: running a section

For most 91-series NCOs, leading means getting work out of a section while the priorities above you change every day. Show how you managed that, beyond holding the title.

Weak:

o led a team of mechanics and set the example by working alongside them every day

Strong:

o led 9 mechanics through 4 concurrent services and a 3-week field exercise; daily work-order board cut average repair time from 6 days to 3.5

Saying you lead by example is only a claim. A repair time that dropped from six days to three and a half is evidence. Include what was pulling at you, such as competing missions, thin parts, or short timelines, because that context makes the number believable.

Develops: your mechanics are the product

Maintenance sections take in brand-new Soldiers and send out capable ones. That is exactly what Develops is for, and most NCOs write it vaguely.

Weak:

o mentored junior Soldiers and provided on-the-job training to improve technical skills

Strong:

o trained 3 new mechanics through sign-off on all skill level 1 tasks in 90 days; 2 of 3 now perform scheduled services without supervision

Another strong example:

o ran twice-monthly mock boards for 2 SPCs; both selected for promotion, 1 named battalion Soldier of the Quarter

Count the Soldiers, name the outcome, and say what they can do now that they couldn't do before.

Character: a decision that cost something

In motor pools, Character tends to get the same recycled sentence every year. The fix is one decision with something at stake.

Weak:

o maintained the highest standards of integrity and honesty in all dealings

Strong:

o refused to release a vehicle for a same-day convoy after finding a scored brake rotor; replaced it in 3 hours and the convoy left on time

The bullet never uses the word integrity. The decision under schedule pressure shows it. This block also needs your rater's comment on dignity and respect and SHARP, so hand them something specific for that too.

Presence: composure and fitness

Presence covers bearing, fitness, confidence, and resilience. For maintainers, the best material usually comes from recovery missions and long field problems.

Weak:

o displayed outstanding military bearing and confidence at all times

Strong:

o led a 4-Soldier recovery team through a 9-hour night recovery of a rolled LMTV in freezing rain; no injuries, vehicle back in the motor pool by 0600

A fitness test score belongs here too if it stands out. The Army now calls it the Army Fitness Test (AFT).

Intellect: show the problem you solved

Weak:

o demonstrated sound judgment and strong technical knowledge

Strong:

o found 14 parts requisitions stalled on a wrong DODAAC; corrected and re-sent them, and 2 other companies adopted the fix

A rater can see a solved problem. "Analytical" is just a word.

The rater's overall comment

Part IV ends with the rater's overall performance assessment, and that block needs at least one bullet too. DA PAM 623-3 says these comments should compare the NCO with peers of the same rank. If your rater has several motor sergeants, a line like this one carries weight:

o ranked #1 of 5 SSGs rated; picked over 2 SFCs to run battalion recovery operations

A ranking only works if it's true and your rater is willing to sign it. Senior raters write their own narrative in Part V. On the SSG-and-above forms, their "most qualified" box is limited to 24 percent of their ratings in a grade.

Turning a normal week into bullet material

Most of your week doesn't feel worth writing about until you count it.

Everyday task	NCOER version
Ran scheduled services	"o completed 62 scheduled services on time; zero overdue at the brigade CMDP inspection"
Managed the deadline list	"o cut deadlined vehicles from 19 to 4 in 10 weeks by ranking parts orders by mission impact"
Supported a field problem	"o ran a 5-mechanic contact team for a 14-day exercise; brought back all 31 vehicles under own power"
Handled the tool room	"o reconciled section tool and TMDE inventory with zero shortages for the first time in 3 inventories"
Generator support (91D)	"o kept 6 tactical generators running for a 10-day CPX; no unplanned power loss to the TOC"

Each row has the same three parts: the task, the count, and what it meant for the unit.

Before it goes up the chain

Check each bullet against the rules first. Two lines at most, starting with a lowercase "o," in past tense, with each example used once. Then read it aloud. If it would fit on any other motor sergeant's NCOER in any other battalion, it isn't specific enough. "Maintained vehicles to standard" fits everyone. "Raised FMC from 71% to 93% across 74 vehicles" fits one NCO's rating period.

If you're looking at a blank block and a stack of work orders, paste the rough version into the bullet generator, deadline numbers and shop shorthand included. It writes tailored NCOER text, which gives you a draft to cut down and check against your own records.
