Various military record archives from the period indicate that there were five (5) persons named James Hunt in the US ARMY from MISSOURI during WW2.Archived records being what they are this number is likely short of the actual number from that State. (Over 250 individuals by that name are listed from all US ARMY enlistments inclusive of all states and territories.)
Of the five from Missouri, one is African-American; one is from Kanssas City, and three are fromSt. Louis City (a County unto itself).Of these three one was born in 1902 and the second in 1912.The third was born in 1924.This last individual deceased in 1993.
Because the archived data is only 80% complete, the above material is NOT conclusive in answering your question.
It would be an error to presuppose that the deceased individual is the object of your search.
