The Navy as a whole, and Submariners in particular, really do speak a different language. While each occupation has its own acronyms and key words and tricky phrases (in my current job, I often find myself saying things like, "I'm taking this FOUP down to CMP and then going to talk to the MT about those SEM CDs"), but I think that submarining is among the "worst" at being understandable to someone who comes in off the street and tries to follow a conversation. From a VIP cruiser in AMR hearing the announcement "AEA, 2JV" to a visitor to the bridge being told to be careful of the bear trap when coming down the ladder, I would venture to guess that our terminology is among the hardest non-Mandarin languages in the world to learn.
