Which of the following is NOT a stimulus that will help you go direct to threat?

• A. Blood
• B. Smoke
• C. Brass
• D. Bodies

Answer: (C)

In dynamic entries, you move toward the source of danger by reading environmental cues that signal where the threat is or has recently been. Blood, smoke, and bodies are strong indicators of danger in or near the area, giving you immediate, actionable information about where the threat may be and how close you are to it. They guide your path to engage quickly and stay oriented to the threat’s presence.

Brass, or spent cartridge cases, does not reliably tell you where the threat currently is or whether it remains active. Casings can be scattered by wind, distance, or movement and don’t pinpoint the attacker’s location or posture. Because of that, brass doesn’t serve as a dependable cue to move directly toward danger.
