U.S. Army Hook & Loop Morale Patch

A white five-pointed star outlined in black with a yellow border and set upon a black field which itself is bordered in yellow and black stripes—can actually be traced back not to the stars of the flag, but a World War II operational directive written to decrease friendly fire. Army Regulation 850-5, published in 1942, specified that a “white five-pointed star will be the national symbol of all motor vehicles assigned to tactical units.” Big cap sold separately here
