At JFCOM we were have this conversation with a Navy Capt. in my office, well, just talking about acronyms. The Capt is an SSN captain, so we were talking about this and I innocently brought up FTN! He gave me a "look" then I said "Fast Tracking Nuke!" This always controlled individual, just busted out! I loved doing that ;) Actually he was very surprised with my knowledge of "submarine anatomy?" It's all Good!
