Final answer:
A Technical Sergeant i.e., two current and two former enlisted ranks in the United States Armed Forces is at pay grade E-6, which denotes rank, responsibility, and pay within the military pay scale.
Step-by-step explanation:
The pay grade for a Technical Sergeant in the United States Air Force is E-6. This is part of the enlisted pay scale, which ranges from E-1 to E-9, and each level corresponds to an increased level of responsibility, experience, and pay. The General Schedule mentioned in the reference, though related to federal civilian employment pay scales, does not apply to military ranks and their associated pay grades.
