A theory of explanation might treat explanations in either a realist or an epistemic (that is, anti-realist) sense. A realist interpretation of explanation holds that the entities or processes an explanation posits actually exist--the explanation is a literal description of external reality.
Officers in pay grades O-1, O-2, and O-3 with more than four years of prior cumulative service in an enlisted or warrant officer grade are paid increased wages using the special pay grades of O-1E, O-2E, and O-3E, respectively.
Sample Grade Structure A simple grade structure might look like this: Grade Salary Minimum Salary Midpoint Salary Maximum 1 $7,500 10,000 12,500 2 9,500 12,000 14,500 3 11,500 14,000 16,500 4 14,000 17,000 20,000 I've used round numbers here. The salary midpoint of a grade is typically 20-30% higher than the preceding grades salary midpoint. â¢ The maximum of a grade may be higher than the minimum of the next higher grade (but doesn't need to be).
