What is the personnel limit for a 274 team?

The personnel limit for a 274 team is determined by the operational requirements and the capacity to effectively manage munitions handling, including safety protocols and efficiency in operations. In this context, the correct answer indicates that a 274 team is appropriately staffed with up to 78 personnel and can include an additional 10 casual personnel.

This specific limit is rooted in guidelines that ensure teams are adequately prepared for the tasks they perform, balancing safety and operational efficiency. Having 78 personnel allows for a robust team capable of handling the complexities involved in munitions management while also enabling support from casual personnel when needed, thus creating flexibility in staffing to address peak operational demands or increased workloads.

The figures provided in the other options would not provide a sufficient number of personnel for the typical operational requirements expected of a 274 team, potentially compromising safety and efficiency in munitions handling.
