What privilege did Surgeon's Stewards have regarding discharge from the Navy?

Surgeon's Stewards in the Navy were granted the privilege to be discharged only with the consent of an officer. This means that Surgeon's Stewards, who held a position that combined medical knowledge with military service, did not have the autonomy to leave the service without formal approval. This requirement ensured that their departure would be managed according to the needs of the Navy and the circumstances surrounding their service and responsibilities. It underscores the importance of maintaining a structured chain of command in military operations and preserving the continuity of care, especially given the medical responsibilities these personnel would have had.

The other choices describe scenarios that do not align with the regulatory framework at the time for such positions. The concept of discharge at will would disrupt military order and detract from operational effectiveness, while automatic discharge after a set time frame or discharge solely after a specific duration lacks the necessary oversight that was essential for maintaining medical readiness and personnel management.
