Limited duty (LIMDU) is the assignment of a
member of a duty status, following a medical boards
action, for a specified period of time with certain
medical restrictions on the duties that a member may
perform. The following information as well as
information contained in the Manual of the Medical
Department, NAVMED P-117; the MILPERSMAN,
Article 1830120; and the Enlisted Transfer Manual
(ENLTRANSMAN), chapter 27; will help you when
you counsel members concerning LIMDU.
One of your responsibilities as a PN1 or PNC is to
inform and counsel personnel about the limited duty
designators that they may be assigned in view of

particular limited duty designator. Limited duty
designators are described as follows and in the
MILPERSMAN, Article 1830120.
Foreign nationals who are enlisted or inducted and
