Which standard operating procedure is referenced for CLZ operations?

The reference to BMU-1 SOPs as the standard operating procedure for CLZ operations is correct because these procedures are specifically designed to outline the protocols and responsibilities for managing Combat Landing Zones (CLZ). The BMU-1 SOPs provide critical guidelines that ensure safety, efficiency, and compliance with military standards during air operations in designated landing zones. This includes coordination of aircraft movements, communication protocols, and contingency plans for emergencies, making it a vital resource for personnel involved in CLZ operations.

Other options, such as Sea-Ops, Naval Operations Manual, and Joint Airborne SOPs, may cover various aspects of military operations but do not specifically address the unique requirements and procedures for CLZ operations, thereby making them less applicable in this context.
