Matt,

It's an artillery training group photo. It wouldn't be possible to trace his unit with this info. After he graduated artillery training he would probably have been assigned to another unit for deployment.

"Pack" refers to the Pack Howitzers, the small artillery pieces shown in the photo. They were used in close terrain, heavy jungle fighting or disassembled and carried on mules in mountainous terrain, for infantry support artillery. The term "pack" means, able to pack around or to carry as on a "Pack Mule".
