I'm doing some research on my grandfather who was in the Army 33rd division 136 infantry during WWII. I was going through his foot locker of stuff and found a couple things I don't know what they are. any help would be appreciated.
welcome to the Forum! I would assume beings the 33rd went to Hawaii in 1943 and then on to New Guinea that those are Japanese items and appear to be collar tabs or rank insignia.
The middle patch looks like it could be that of a corporal (Go Cho) if the darker parts were originally yellow. http://www.uniforminsignia.net/index.php?option=com_insigniasearch&Itemid=53&result=1353
