Final answer:
In cases of punishment that includes both a reduction in rate and forfeiture of pay, the forfeiture is based on the reduced paygrade.
Step-by-step explanation:
In the case of punishment that includes both a reduction in rate and forfeiture of pay, the forfeiture is typically based on the reduced paygrade. Therefore, the statement is true. For example, if a person's paygrade is reduced due to a punishment, any pay that is forfeited will be calculated based on the reduced paygrade, rather than their original paygrade.
