After recieving some paperwork from family, turns out my grandfather was in the 11Th. A.D. HQ section, as the Batt. Surgeon. Looks like Gen. Dager was in charge.
I have found some info. on the unit, but I am not entirely sure of the exact duties of that position(strictly management or use in the field, etc.). If there is anyone out there with any info or other possible resources, that would be helpful. The 11th. Armored website has been a great resource, just wondering if there might be other area to look. Thanks.
