Interesting find, is the chain attached? The Combat Infantryman Badge hasn't changed since it's inception (1941). Typically the wreath denotes combat service in the specific MOS, infantryman and medic only. The 2 MOS's were originally the only 2 awarded a badge for action under fire. Now there is a CAB (combat action badge) as well. I agree with others, it appears to be a sweetheart pin or something of a sort. It may be one-of-a-kind! I'm almost positive it didn't belong on an official uniform....
