Army OER Writing Tool for Officers

What the OER is and who writes it

The Officer Evaluation Report (OER) is the Army's evaluation for commissioned officers. Like the NCOER, it comes in versions for different grade groups: company grade lieutenants and captains, field grade majors and lieutenant colonels, and strategic-level colonels.

The rater describes performance, and the senior rater compares the officer with peers and comments on potential. Those senior rater words often decide promotion and command selection, so officers prepare support forms and draft input carefully.

Officers who prepare well usually start long before the report is due. They keep a running file of results, note the size of formations and budgets they led, and record moments where they made a tough call. That file becomes the raw material MilPath turns into draft comments, and it makes the conversation with the rater far more productive.

How Army OER writing differs

OER comments are narrative paragraphs rather than lists of bullets, and the most valued phrases are about potential: whether the officer should command, attend school, or be promoted ahead of peers. Strong performance comments set up that recommendation with evidence.

Compared with the NCOER, OER writing is less about individual tasks and more about leading organizations, managing complexity, and developing subordinate leaders. Compared with the Air Force OPB, the Army splits performance and potential more clearly between rater and senior rater.

The best OER input reads like evidence handed to a lawyer. Raters and senior raters are busy, and they often write in a small window of time. When an officer's support form clearly shows the size of the formation, the hardest problem solved, and a measurable result, the rating chain can write stronger narratives faster. Vague claims like being a great leader give them nothing to work with, and board members tend to skim past them.

How to use MilPath for your OER

1. In the Bullet Generator, choose Army and select OER (Company Grade), OER (Field Grade), or OER (Strategic / Colonel).
2. The grade-specific format tells the AI which version of the OER you are writing for.
3. Enter the officer's accomplishments and the organization involved, then generate.
4. Use the drafts as material for your support form or for the rater's narrative.
5. Review every claim with the rating chain before it goes on the report.

  After: Synchronized logistics for a 3-battalion exercise, moving 400 vehicles on time and under the planned fuel budget.

• Before: Mentored lieutenants.

  After: Built a professional development series for 8 lieutenants; 3 were selected for competitive key positions within a year.

• Before: Handled the budget.

Tips

• Tie performance comments to the potential the senior rater will recommend.
• Show the size and complexity of the organization you led.
• Name the leaders you developed and what happened to them.
• Keep company-grade drafts at company-grade scope; overreaching reads as inflation.
