Final answer:
A special evaluation for an E-6 should not be submitted because it is not required at that rank.
Step-by-step explanation:
A special evaluation for an E-6 should NOT be submitted for the reason that it is not required at that rank. E-6 in the United States military, also known as a Staff Sergeant, has already reached a level of experience and proficiency where special evaluations are not necessary. Special evaluations are typically used for promotions or to identify exceptional performance, but at the E-6 level, regular evaluations are sufficient.
