Marcus Luttrell, author of Service: A Navy SEAL at War, talks to Brendan McKnight before signing his book at the Vero Beach Book Center. McKnight was headed to boot camp the following Monday. “I was sitting there 16-years ago,” said Luttrell of boot camp. “You’re not going to believe how bad it is.” During boot camp Luttrell didn’t think they were keeping him in shape. “I had to sneak out of my division at 4:30 a.m. to train with the SEALS.” Staff photo: Keith Carson.
