There exists one post, Master Chief Petty Officer of the Navy, (MCPON, pronounced "Mc-Pon") which is unique. The holder of this post is the most senior enlisted member in the U.S. Navy. The MCPON adds a third inverted star above the rating insignia described earlier, and all three stars are gold (silver on the gold fouled anchor collar device). Likewise, the rating specialty mark is replaced by an inverted gold star. On July 10, 2006, Joe R. Campa assumed the role of MCPON, replacing Terry D. Scott.
