82nd Airborne 504th at Nijmegen

On behalf of the family, I am looking for any information concerning Master Sergeant John W. Tangas, Army No. 36053158
John served in Tunesia, Sicily, Anzio and Nijmegen as member of the 504th. The citation for his Silverstar concerns Nijmegen, where he crossed the Waal river and got wounded on the north side of the river around 21st of September 1944. The children want to visit Nijmegen in 2026 and would like to retrace the footsteps of their father. Most important question, What was his Battalion and his Company, this would narrow down our search considerably. Any help is very much appreciated.
