My Dad was a Radio Man in the 45th Infantry Division, the Thunderbird Division, originally a National Guard unit out of the Southwest. He was with them from North Africa, Sicily, Salerno and Anzio where he was wounded just after.
Dad was Portuguese decent from Provincetown, Mass. He said he was drunk and ended up on the wrong train.
Anyway..Dad understood Italian but he always had to have a Native-American with him to do the talking on the radio.
Interesting, thank you, Wilum.
