This is the Sniper's Badge (Third Class) that Hitler established in 1944:
Soldiers were told to remove it if they were at risk of being taken prisoner as the Russians would shoot men wearing the badge. Stalin, like Hitler, was afraid of assassins but not opposed to having snipers in his army.
Again you are missing the point which is that all tyrants hate anyone that can oppose them with lethal force and a sniper can do so as one man with one shot. If this is not clear to you then I can do not better in explaining.
BTW cool patch enjoyed seeing it.
