COC -Combat Operations Center. It's actually pronounced as cee-oh-cee, but when you you put a half-dozen or so young enlisted guys who think that sex jokes are the highest form of humor in it, the pronunciation magically becomes phonetic.
CINCUS- Commander-In-Chief-US fleet. Possibly the most unfortunate-sounding acronym ever.
HMMWV- High-Mobility-Multi-purpose Wheeled Vehicle. Often pronounced as "Hum-vee". Nothing wrong with the acronym itself, other than that many service-members think it means High-Mobility Multi-Wheeled Vehicle. While this is an understandable error given the large number of combat unicycles we field, it is nonetheless incorrect and somewhat annoying. The term "high-mobility" is also somewhat subjective.
