Start Talking Like a Sailor

You’ll want to start practicing this lingo long before you head to the Recruit Training Command Center in the Great Lakes.

You may not use these Navy terms every day aboard the ship, but you’ll want to know titles and ranks quite well.

Once you get a copy of The Bluejacket’s Manual at boot camp, you’ll also find an updated dictionary with military terms to refresh your memory.

In the meantime, learn the lingo and pass this list along to family members and friends. That way they’ll know exactly what you’re talking about once you start exchanging letters while you’re in boot camp!
