What is the tactical benchmark for an area that has been searched and cleared?

The designation "All clear" is used as the tactical benchmark for an area that has been searched and cleared. This term indicates that a thorough search of the area has been conducted and that no threats or hazards have been identified, allowing personnel to safely proceed or occupy the space. It reflects a level of assurance that the area is secure and no further action is needed regarding threats to safety within that specific location.

Other options do not reflect the context of searching and clearing an area. "Under control" implies that a situation is being managed but does not signify that the area is completely cleared of threats. "Evacuation complete" pertains to the successful removal of individuals from a site, and while it may follow a search, it does not denote that the area has been examined and deemed free of threats. "Fire extinguished" specifically addresses fire hazards, which is unrelated to the general benchmark of searching and clearing an area for security purposes.
