My Dad was a senior enlisted man in the 421st and served on Okinawa. I have very little information about his service, but do have a few pictures I will post soon. What he has told me tracks with the unit history and with what others have posted. My impression is that his service was tougher than any of us might expect. The extra duties dealing with the dead soldiers and civilians were upsetting. Please tell me if you have him listed in any documents. Thanks and I am glad I found you.
