I am not familiar with a military term "Collective"however "Collecting" might be more appropriate.
411th could possibly refer to elements of the 11th Airborne Division, and I find a 411th QM Company attached in Pacific opertions.
Whether he was attached in combat or not is obviously to be determined, but in reference to the patches you have, maybe this will get you thinking outside the box...Late in the war transfers of units from ETO to PTO was contemplated under the direction of 6th Army GROUP (ETO)--he may have been involved in this opertion with responsibilities to 6th ARMY(PTO)--They are two different things...
"6th Army Group, commanded by General Jacob L. Devers, has been assigned the task of training all ground forces which will move from the European Theater to the Pacific, either direct or by way of the United States.
Two combat and one service training headquarters will be set up under the 6th Army Group, under which training will be received by the divisions and other ground units slated to go to the Pacific.
Gen Devers' headquarters, coordinating and exercising general supervision of the redeployment training program, will be in Heidelberg, Germany.
The plan is to train combat and their organic service units in the Zone of American Occupation. Probably ten special training areas, each suitable for accommodating a division and its necessary attached units, will be required as training centers. If time permits all combat units will be given eight weeks of specialized training before leaving for shipment. Most service units, exclusive of those organic to combat units, will receive their redeployment training while performing their present work at their present stations."(Source: Army and Navy Journal, June 16, 1945)
