Who has final approval on parts over $2,000 but less than $5,000?

The correct answer indicates that the Commanding Officer (CO) has final approval authority for parts that are priced between $2,000 and $5,000. This reflects a structured system of oversight and responsibility in operational environments, particularly in military or organizational settings where procurement authority needs to be clearly defined to ensure accountability and proper resource management.

The CO's role typically includes overarching command responsibilities, which often extend to financial decisions involving asset management and expenses incurred by the unit. Their approval signifies a level of control that is essential in managing budgets effectively and ensuring that all expenditures align with the organization’s strategic goals.

Although the other roles mentioned, such as Department Head (DH) and Supply Officer (Suppo), have significant responsibilities regarding parts and may handle approvals or recommendations in different contexts, the CO's authority in this price range typically ensures that higher-level oversight is maintained. The approach of having final approval through a centralized figure helps mitigate risks associated with unauthorized spending and supports compliance with fiscal policies.
