I found this on the net it will tell you what CDD means. As far as what 2nd Ind. HQ, it could be 2nd Infantry Headquarters. You can google what CDD means in the Army and see what other info you can find.
Well, not all discharges for disability were made with compensation. CDD means Certificate of Disability for Discharge, which means a board of doctors made the determination that he could/should be discharged. As far as I can tell, Section II dealt with neuropsychological cases.
"Under the provisions of section II, AR 615-360, and later, AR 615-361, issued on 4 November 1944, the neuropsychiatrist was frequently appointed as a member of the board of medical officers generally referred to as the “CDD (certificate of disability for discharge) Board.” Even more frequently, however, he presented neuropsychiatric cases before this board which determined whether disposition would be accomplished by medical discharge. A major involvement of the psychiatrist with this board was the determination of the line of duty relative to disposition and commitment of psychotic patients. Those cases of psychosis whose line-ofduty status was determined to be “yes” after prior presentation before the “600-500 Board” (p. 476) offered little difficulty in disposition except for a reasonable delay when transfer to a Veterans’ Administration facility was necessary. Patients requiring continued psychiatric hospital care, whose illness was not considered to be incurred in line of duty, presented considerable difficulty in disposition, especially early in the war.
Many chronic minor offenders, mental defectives, “alcoholics,” psychopathic states including sexual deviates, and other personality disorders were referred for psychiatric evaluation but could be discharged from the service only by nonmedical (administrative) proceedings. These cases were usually first sent for psychiatric evaluation and then, if deemed appropriate, were referred to “Section VIII” boards. This section of the general regulations (AR 615-360, 26 Nov. 1942), dealing with premature separation from the service, provided for the release from active duty of a wide variety of behavioral problems under the heading “inaptness or undesirable habits or traits of character,” as follows:
(1) Is inapt [included mainly intellectual deficiency], or
(2) Does not possess the required degree of adaptability for military service [included enuresis and personality disorders who manifested little or no acting out behavior] * * *, or
(3) Gives evidence of habits or traits of character [included acting out behavioral disorders, alcoholism, and sexual perversions as homosexuality] * * * which serve to render his retention in the service undesirable * * * or,
(4) Is disqualified for service, physically or in character, through his own misconduct [included mainly individuals injured and rendered disabled during the commission of a military or civilian offense], and cannot be rehabilitated so as to render useful service before the expiration of his term of service without detriment to the morale and efficiency of his organization * * *.
