Notes:
The US Army Specialist 5 (Spec 5 or E-5) was a discontinued technical rank used from 1955 to 1985. Designed to reward soldiers with specialized skills without giving them traditional leadership (NCO) authority, it was ultimately phased out because the Army transitioned to a simpler rank structure.
