Re: [jidavis] 315th Air Transport Service Group
I will repeat this here as well:
There is no such unit named Air Transport Service Group.
It may be the 315th Air Service Group or the 315th Air Transport Group, or it could be the 315th Troop Carrier Group.
The 315th Troop Carrier Group was called the 315th Transport Group prior to redesignation. This is the most likely unit, and the the only one found in the current database.
