I, for a time had a strong interest in joining the military. I now realize I would have been a disaster.
Disqualifications, and keep in mind that many disqualifications remained even during the Second World War (a time we didn't know as much about these areas):
Quote:
Disorders with psychotic features
The causes for rejection for appointment, enlistment, and induction are disorders with psychotic features.
Neurotic, anxiety, mood, somatoform, dissociative, or factitious disorders

Personality, conduct, and behavior disorders
The causes for rejection for appointment, enlistment, and induction are:

b. Personality, conduct, or behavior disorders where it is evident by history, interview, or psychological testing that the degree of immaturity, instability, personality inadequacy, impulsiveness, or dependency will seriously interfere with adjustment in the Army as demonstrated by repeated inability to maintain reasonable adjustment in school, with employers and fellow workers, and with other social groups.
c. Other behavior disorders including but not limited to conditions such as authenticated evidence of functional enuresis or encopresis, sleepwalking, or eating disorders that are habitual or persistent occurring beyond age 12, or stammering of such a degree that the individual is normally unable to express himself or herself clearly or to repeat commands.
d. Specific academic skills defects, chronic history of academic skills or perceptual defects, secondary to organic or functional mental disorders that interfere with work or school after age 12. Current use of medication to improve or maintain academic skills.
