Medical Standards for Enlistment, Appointment, or Induction

Disqualifying Medical Issues

Military Medical.

There are many reasons why the military does not allow people with certain medical conditions to join the ranks.  Mainly the reason is for safety of all service members.  Also not being able to care for and treat major ailments, and some injuries / illnesses that will prevent function of the daily duties of the ill service member can be dangerous if no medical resources are available for long periods of time.

 Many deployments with no access to medical facilities occurs all the time within the Navy (ships and submarines) as well as forward deployed bases in the other branches (Army, Marine Corps, and Air Force.)

The information  in the links below are derived from the publication DODD6130.3 and DODI6130.4.  It provides complete information on all the medical fitness standards for induction, enlistment , appointment, retention, and related policies and procedures.

(2) Free of medical conditions or physical defects that would require excessive time lost from duty for necessary treatment or hospitalization or would likely result in separation from the Army for medical unfitness.

(3) Medically capable of satisfactorily completing required training.

(4) Medically adaptable to the military environment without the necessity of geographical area limitations.
