armory
An armory is any location designed for the safe storage and access of weapons, armor, and ammunition. Tag only if there is a rack showcasing weapons, armor, or ammunition or if it is otherwise apparent from the image that it is an armory.
A sub-armory is a temporary location (such as a guard post) that can function as an armory under proper supervision. For the purpose of tagging, this is the same as an armory.
