Duty Assignments

Assignment of all members to OHSU WRNMMC Bethesda detachments is centrally managed through the OHSU Bethesda Command Headquarters.

If you are on officer, you will meet with the Command Manpower Officer and the Senior Corps Executive to discuss your background, qualifications and professional goals. If you are enlisted, you will meet with the Senior Enlisted Advisor to discuss your background, qualifications and professional goals. Once this is concluded, a determination will then be made as to which detachment will be most suitable for assignment balancing your personal preferences with the needs of the Command.
