Routine drills are based on ship's bills and stem from the basic bills outlined in which publication?

The correct choice highlights the significance of the "Standard Organization and Regulations of the U.S. Navy" as the foundational document for routine drills on a ship. This publication outlines the structure, operations, and policies that govern naval activities. It provides the framework for the organization of the ship’s company and details the responsibilities and requirements for personnel during various operations, including drills.

Routine drills are crucial for ensuring that crew members can efficiently respond to emergencies and execute their roles effectively. By adhering to the guidelines set forth in this publication, the crew is able to standardize their drills, ensuring that every member understands their duties in a coordinated manner.

While U.S. Navy Regulations also provide essential protocols and guidelines that influence operational behavior and expectations, it's the specific structuring and organizational directives found in the "Standard Organization and Regulations of the U.S. Navy" that are foundational to establishing the routine drills and ship's bills essential for operational readiness. The Refresher Team Training Manual, while important for specific training protocols, does not serve as the central document governing routine ship drills.
