Which document would you refer to for information on rigging procedures?

The correct document to refer to for information on rigging procedures is TM 4-48.10. This technical manual specifically focuses on sling load operations and provides comprehensive details about the techniques, procedures, and safety measures involved in rigging loads for air transportation. It serves as a critical resource for understanding how to properly prepare and secure loads for aerial delivery, ensuring that the rigging is conducted safely and effectively. By consulting this manual, operators can access the necessary guidelines and step-by-step instructions that are essential for successful sling load operations, which is critical for mission success and safety.

Other choices, while related to military operations and logistics, do not focus specifically on rigging procedures for sling loads. For example, FM 4-20.102 and FM 3-21.38 deal with broader topics concerning logistics and tactical operations, respectively. TM 4-48.11 again focuses on related aspects but is not the primary source for rigging techniques and procedures. Thus, TM 4-48.10 stands out as the definitive guide for this specific area.
