Which term is associated with signals for wake-up and activity start?

The term associated with signals for wake-up and activity start is "Reveille." This signal has a long-standing tradition within the military, serving as a call to attention that usually occurs early in the morning, marking the beginning of the day’s activities. Reveille is typically played to wake up personnel, indicating the start of their duties and the official beginning of the day’s schedule. It is an important ritual that fosters discipline and alertness among service members.

In contrast, "Scuttlebutt" refers to gossip or rumors, traditionally associated with sailors gathering around a water fountain. "Liberty" signifies the permission granted to service members to leave their duty station for a specified period, often a break from military responsibilities. "Lifeline" generally pertains to safety measures or support systems in various contexts, rather than signaling the start of daily activities. Therefore, "Reveille" is specifically linked to the wake-up call and the initiation of daily routines for military personnel.
