I'm trying to make sense of what units/locations my Grandfather served. Unfortunately he is deceased but I do have some of his documents, and/or possessions that may lead to clues. I'm especially interested in what units he served and/or how did he get campaign credits when his unit did not receive them. Here is some of his information: 1. Inducted: 27 Mar 1940 (From Honorable Discharge Report) 2. Arrived Hawaii (Schofield Barracks): 27 May 1940 (Possibly with the 24th Inf Div) (Oral through wife) 3. Survived the attack and went inland to shore up defenses (oral history) (Oral) 4. Campaign Credits (From Honorable Discharge Report): Central Pacific, Eastern Mandates (Kwajalein - Oral account), Southern Philippines, Ryukus 5. Medals on Discharge Papers: Good Conduct Medal (no devices), Asiatic Pacific (4 B.S. with Arrowhead), Philippine Liberation (2 B.S.), American Defense Service Medal (1 B.S.) (From Honorable Discharge Report) 6. Date of Return to US: 16 Aug 1945, Date of Discharge 22 Aug 1945, ASR Score 125, 73 Days Lost under AW 107 (for driving through the Dole Plantation-Oral History) 6a. After Ryukus, he returned briefly to Hawaii, and was heading for Japan for the "Big Invasion" and troop ship was turned around for dis-embarkment to the US (Oral History) 7. Organization Co B, 767th Tank Battalion (From Honorable Discharge Report and Discharge Certificate) 8. Army Qualification Separation Record (22 Aug 1945): 746 Autorifleman (9 months/Pvt), 745 Rifleman (1 year/Pvt), 531 Cannoner (5 months/PFC), 1736 Lt Tank Crewman (2 months/Sgt), Med Tank Crewman (1 yr-6 mths) Sgt (Later PANG paperwork says he was a Rifleman III throughout the war) Here are the glowing problems I'm having that someone might shed some light: Assuming he stayed with the 767th Tank Batallion when he converted from Rifleman to Tanks, how did he get credit for other campaigns while his unit did not? Transfer? I'm thinking his 1736 Lt Tank Crewman of 2 months was with another unit? What units had Light Tanks? Any thoughts would be appreciated!
