Which reference material covers dual point rigging procedures?

The reference material that covers dual point rigging procedures is TM 4-48.11. This technical manual specifically addresses the techniques, procedures, and safety measures associated with rigging loads for air movement operations, making it essential for understanding the complexities involved in dual point rigging. This manual provides detailed instructions and guidelines necessary for the safe execution of operations involving the simultaneous transport of a load by two lifting points, which is a critical skill for air assault operations.

The other choices focus on different aspects of military operations and rigging. For instance, while FM 3-21.38 pertains to air assault operations more broadly and may include some rigging information, it does not specifically target dual point rigging. TM 4-48.04 deals with general rigging procedures but does not focus on dual point techniques specifically. Lastly, TM 3-20.22 addresses other tactical operations and does not cover rigging at all. Thus, TM 4-48.11 is the most relevant and specific reference for dual point rigging procedures.
