The army's technician grades were technical and professional specialists similar to the later specialist grade. Technicians had the same insignia as NCOs of the same grade but had a "T" insignia (for "technician") beneath the chevrons. They were considered the same grade for pay but were considered a half-step between the equivalent pay grade and the next lower regular pay grade in seniority, rather than sandwiched between the junior enlisted (i.e., private – private first class) and the lowest NCO grade of rank (viz., corporal), as the modern-day specialist (E-4) is today. Technician grades were usually mistaken for their superior NCO counterparts due to the similarity of their insignia, creating confusion.
