"And it was that sailor who guided my own resolve to raise the bar on the headquarters staff to execute our man, train and equip mission to the fullest effectiveness possible."<br /> <br /> Moss is a graduate of the United States Naval Academy and was commissioned an ensign in 1983. Moss will retire after serving 34 years in the Navy. <br /> <br /> Peterschmidt is a graduate of Marquette University and was commissioned an ensign in 1987. He previously served as Commander, Littoral Ship Squadron One and was directly involved in deploying littoral combat ship USS Freedom (LCS-1) on her first Western Pacific deployment to Singapore in March of 2013.<br /> <br /> "I'm excited to be joining this professional group of sailors and leading them in dynamic and vital mission sets that are important to our Navy and nation," said Peterschmidt. "Having survived a waterborne improvised explosive attack, I fully understand the nature of the threat that we face today and how this command can serve to prevent such attacks again in the future." <br /> <br /> Coastal Riverine Force operates in harbors, rivers, bays, across the littorals and ashore.
