For your consideration is this decent condition U.S. Air Force Unit Shirt for the 51st Force Support Squadron based out of Osan Air Base in South Korea. This is unbranded and has no sizing on it. The shirt measures closest to a men's small. It is royal blue in color. The most noticeable defect is some discoloration on the face of the righr shoulder that may be some light bleaching. Otherwise, it remains a very wearable shirt.
