APSS Perch 313, page 57
Paul Munsch sent these pictures which were taken in late 1963 or early 1964.  Those with printed captions were from a newspaper article on the Perch.  The one showing South Viet Nam UDT trainees was taken off  Viet Nam. Paul said he is in the picture along with Chief Martinez, but Paul didn't know the names of the other Perch sailors in this particular photograph.
