Technician 5th Grade - abbreviated "Tech5" or "T/5" - was a specialist rating which shared the 5th Pay Grade with the rank of Corporal (there were seven enlisted pay grades - 7th [lowest] through 1st). There were two other ratings, Technician 4th Grade and Technician 3d Grade, which corresponded to the ranks of Sergeant and Staff Sergeant, respectively. Technicians had no command authority but, by the end of the war, the titles Tech5 and corporal (Tech4 and sergeant, etc.) had come to be interchangable. These were discontinued in 1948. The nearest present day equivalent would be Specialist, Pay Grade E-4.
