Which command indicates the weapons are locked and secured?

The command that indicates the weapons are locked and secured is "Stowed." This term is commonly used in military and law enforcement contexts to denote that weapons are not only secured but also stored in a manner that prevents their use until they are needed again. When weapons are stowed, they are typically placed in a designated storage area, ensuring that they are adequately protected and cannot be accidentally discharged.

The other terms, while they may refer to different states of readiness or condition of weapons, do not convey the same level of security. For example, "Free" usually implies that the weapon is in an open or accessible state, "Ready" suggests that the weapon is prepared for immediate use, and "Action" implies that the weapon is in a state of functioning or being used. None of these terms reflect the locked and secured status that "Stowed" clearly communicates.
