Two people wearing behind-the-neck earmuffs. Thermal earmuffs are worn for protection from the cold. Because the ears extend from the sides of the head to gather sound waves, they have a high skin surface-area-to-volume ratio, and very little muscle tissue, causing them to be one of the first body parts to become uncomfortably cold as temperatures drop.

Because of the pressures associated with the 5.56×45mm, it is not advisable to fire 5.56×45mm rounds in an AR-15 marked as .223 Remington, since this can result in damage to the rifle or injury to the shooter.
