I'm doing research into my grandfathers service in Luzon during 1945. I'm seeking documents - rosters, after action reports, anything I can find for the 25th Infantry Division, 27th Infantry Regiment during the Luzon Campaign. I know my grandfather was a Platoon Leader in the Cannon Company during Luzon.

 Thank you for posting your request on History Hub! 
 The Textual Reference Archives II Branch (RR2RR) has custody of the Records of the Adjutant General's Office, 1917- (Record Group 407) and the Records of U.S. Army Operational, Tactical, and Support Organizations (World War II and Thereafter) (Record Group 338). Military unit files among these records consist mostly of historical reports, after action reports, unit journals, and general orders. These records do not include personnel information, nor do we have a name index to these records. 
 We have searched our available finding aids for the relevant series in the abovementioned record groups for records of 27 th Infantry Regiment, Twenty-Fifth U.S. Infantry Division during World War II and found the following records: 
 Record Group 407 
 Entry (NM3) 427 
 Boxes 7039-7059 (20 boxes) 
 It is generally the case that company- and battalion-level records are not encountered among the infantry unit records in our custody. It is likely that the information contained in these records was collated and included in the regimental and divisional reports. To be sure, individual battalions and companies can (and often are) referenced in these higher-level records.
