Decoding Honorable Discharge paper.

Jim,
 
For what its worth---
Army Regulation (AR) 625-5, "Officer Candidates," 26 Nov 42,  and
IRTC is Infantry Replacement Training Center
 
Did this occur near the end of the war?  Perhaps he was able to be discharged because there was no place for him?

I think your attachment says "VOC" rather than VOG.  VOC means "Verbal Order of the Commander".  Also, it says "Ltr Hq. IRTC" (Letter Headquarters IRTC)--the "H" was mis-typed.  So, it appears that he was excused from the IRTC for some reason and discharged from the Army honorably--perhaps due to a personal or family emergency or hardship.  Since the discharge was honorable, he wasn't discharged for misconduct or some other unsatisfactory behaviour.  
It looks like you copied only the first part of the paper. Is there any more information farther down in the document (such as code letters)?

 

Just a little more info on IRTC (Infantry Replacement Training Center):
 
"Replacement Training Centers were an integral part of World War II.  Soldier's entering the Army and ultimately the War spent 13 weeks learning the fundamentals of soldiering in one of twenty one Centers that were to be be constructed during the during the Winter and Spring of 1940-1941.    Replacement training centers were opened in March 1941, about six months after the launching of Selective Service. For the remainder of 1941 the recently inducted civilian received his basic training at a replacement center.  By April 1945, approximately 2,500,000 enlisted men had been graduated from replacement training agencies of the combat arm — infantry, cavalry, field artillery, coast artillery, antiaircraft, armored, and tank destroyer."
 
Do you know if he enlisted voluntarily, or if he was drafted?  Does the daughter have any other records (such as his DD-214 form?)
 

Jim,
Thanks for reposting the full pages.  
One more request:  Can you tell us what the very last lines at the bottom of the front side read (the small print below the signatures)?  It looks like it might explain something, but it's very hard to read. Also, on the back, can you make out what is typed in the "Physical Condition When Discharged" line and below that the "Character" line?    I see that he was drafted, but I'm still not sure that age was the main reason for his discharge (although, as Yunch said, it could have been a contributing factor).  It looks like he requested a discharge from the Army under AR625-5 for some reason.  So far I've been unable to find a copy of those Army Regulations online anywhere.

The small print on the bottom of the front page appears to  contain instructions for completion of the form. The name in the first full line is "John J. Doe".  The last three words at the end of the same line are "Sergeant Quartermaster Corps". Directly under these three words is a name that I can't make out.

If you are looking at a version of AR 625-5 that refers to the DD Form 214, it is not a WW II version of the regulation.  The "DD" in DD-214 refers to the Department of Defense.  The World War II discharge form was a War Department Adjutant General's Office (WD AG0) form.  The Certificate of Service was WD AGO Form 280 and the Report of Separation was WD AGO Form 53.
