Recruits at the Recruit Training Center, Great Lakes, Ill., inventory and read a passage out of their freshly-issued Bluejackets Manual. Recruits are required to read the ?From Civilian to Sailor? passage during their first few hours of arriving at the Center for basic training. The Bluejacket's Manual is celebrating a century of teaching Sailors the basics of Navy seamanship and life in the Navy-- including terminology, rank structure, jobs, military drill, and proper wearing and stowing of uniforms. The book gets a major overhaul every four years and is printed every six months. Each edition includes minor updates that ensure the manual is as accurate as possible.
