Why should helmet covers not stick up like plumes?

• A. To improve airflow.
• B. To prevent reflection.
• C. Head movement will give away the position.
• D. To improve camouflage efficiency.

Answer: (C)

Concealment relies on not creating cues that reveal your position. A helmet cover that sticks up like a plume forms a distinct vertical silhouette and can sway with every head movement. Observers—whether trained to notice shapes or just scanning for motion—are likely to spot that protrusion, so moving your head can give away where you are. Keeping the cover flat and flush reduces this conspicuous signature, making you harder to detect. While avoiding glare or thinking about airflow can matter, the most direct reason to prevent a plume is to stop movement and shape from signaling your location.
