What is the term for the assembling of all hands for muster, instruction, and inspection?

The term for the assembling of all hands for muster, instruction, and inspection is "Quarters." This phrase is specifically used in a military context to describe a formal gathering where personnel are accounted for, given instructions, and can be inspected by superiors. During quarters, the commanding officer may also relay important information and ensure that everyone is present and ready for duty.

In a Navy context, quarters serve as an important ritual that reinforces discipline and allows for effective communication among the crew. They help maintain organization and readiness within the unit.

Reveille refers to the morning event that signals the start of the day, calling personnel to wake up and prepare for duties, and is not specifically about inspection or muster. Tattoo is a term used more for the evening routine related to securing the ship and evening duties, while Secure generally pertains to the end of duties or a time to come to a halt after operations. Each of these terms serves distinct purposes within military protocol, further emphasizing why "Quarters" accurately encapsulates the idea of assembly for muster, instruction, and inspection.
