180117-N-IY633-062 GREAT LAKES, Ill. (Jan. 17, 2018) U.S. Navy recruits help each other properly don firefighting gear at Recruit Training Command (RTC). Recruits practice firefighting through hands-on training, which means recruits will 'train how we fight'. About 30,000 to 40,000 recruits graduate annually from the Navy's only boot camp.
