List of Army Branches for Officers: A Complete List

If you are trying to decide what branch of the Army you want to become an officer in, you have come to the right place. There are many options, and it can be a difficult decision. I suggest that you really look inside yourself to determine not only the type of work you want to do in the Army, but also consider your post Army career. The branch you choose can also determine the work you will get after you have served in the Army.

This post can help you if you are in the ROTC, or if you are just considering your future choices in the journey of life. I am posting a complete list of Army Branches for Officers. Now keep in mind that there are certain branches for Officers that can only be attained if you have already received a college degree in that area of expertise. The other branches can be entered by completing Officer Candidate School (OCS).

Special Branches

In the following branches, Officers are usually Direct Commission. This means they attained a degree in the branch before they joined the Army.

  • Medical. The Medical Branch has Officers that can come through OCS, but Doctors, Nurses, and some other specialty Officers are direct commissioned after earning their degrees. This also includes Dental and Veterinary branches.

  • Chaplains. The Chaplain Branch is a direct commission after the individual earns their degree.

  • Judge Advocate General Corps. This Branch is also a direct commission after the individual earns a law degree.
