Charles Portal's RAF Pin

Origin
Charles Portal was a Royal Air Force officer who advocated area bombing over Axis industrial areas. This was meant to destroy a wide variety of targets important to the war effort and to demoralize the enemy, by using the same technique the German Luftwaffe had used on Britain. In retirement Portal was chairman of British Aluminium and unsuccessfully fought in the "Aluminium War" against a hostile takeover bid by Tube investments; he then became chairman of the British Aircraft Corporation.

Effects
Sends projectiles back at their source. Bullets, for example, will hit the shooter in exactly the same places that were targeted. As time goes on the retaliating fire will become more scattered and less accurate.

When active, the pin’s logo will momentarily expand and shrink, feeling warm to the touch. Nearby aluminum objects will make a pained creaking, groaning sort of noise when the projectile is sent back.
