NATO Report Standards & Reconnaissance Techniques Practice Test

In safety and reconnaissance, SLLS is a quick four-part cue to assess surroundings before proceeding. Stop to pause and avoid rushing into potential danger, then Look to visually scan for hazards, obstacles, or threats. Listen for sounds that could reveal movement or alarms you can’t see, and finally Smell to detect hazardous fumes or unusual odors signaling danger. The phrase Stop, Look, Listen, Smell exactly captures this sequence, making it the best answer. Other options replace or add actions that aren’t part of this standard safety mnemonic, so they don’t fit the intended meaning.
