How many sets of T-11R inserts are needed for PJ/AJ and door bundle pushers?

To determine the number of sets of T-11R inserts needed for PJ/AJ and door bundle pushers, it's essential to consider the equipment requirements and configurations used in operations. The T-11R inserts are specifically designed for facilitating safe and effective jumps with various load types, including personnel and bundles.

In this context, the correct response indicates that four sets of T-11R inserts are required. This number typically corresponds to the operational needs for adequate support and safety during jump missions. Each set is designed to accommodate different load configurations, ensuring that all jump scenarios can be managed effectively.

The requirement for four sets ensures that there are sufficient inserts available for the tandem operations conducted by PJ/AJ personnel as well as for bundle pushers during jumps. This redundancy is critical to ensure safety and preparedness for varying operational demands and to maintain efficiency in deployment scenarios.

While other options suggest fewer sets, they would not provide sufficient coverage for the diversity of jump missions encountered in the field. Thus, the necessity for having four sets reflects the comprehensive planning that goes into ensuring safety and operational effectiveness in airborne missions.
