How many supervisory personnel are required for mass operations from a C-17?

For mass operations from a C-17, a minimum of five supervisory personnel is required to ensure safety and effective execution of the jump operation. This number is established to maintain proper oversight of the operation, manage personnel effectively, and coordinate the jumping sequence, which is crucial in scenarios involving a larger number of parachutists. The five personnel can include the Jumpmaster, safety personnel, and additional support roles necessary for monitoring and managing the jump, ensuring that all safety protocols are adhered to, and that the operation runs smoothly. The requirement for this specific number highlights the complexity and potential risks associated with mass drops, emphasizing the importance of having sufficient experienced personnel on site to mitigate those risks.
