Why is the supervisor given responsibility over equipment and supplies?

The supervisor is given responsibility over equipment and supplies primarily because they are closest to the equipment. This proximity allows supervisors to have a hands-on understanding of the operational status and condition of the equipment, which is crucial for maintaining safety, readiness, and efficiency. Being directly involved with daily operations enables them to assess needs, make informed decisions about maintenance, and ensure that supplies are available when needed. Their direct oversight facilitates effective communication with personnel and allows them to promptly address any issues that may arise, thus ensuring that everything is functioning optimally for mission success.
