Chattanooga native completes Marine bootcamp in honor of Fallen Five [photos]

Newly graduated Marines answer their drill instructors as they are released upon their graduation from boot camp at the Marine Corps Recruit Depot on Friday, April 29, 2016, in Parris Island, South Carolina. 379 new Marines graduated from boot camp Friday.

PARRIS ISLAND, S.C. - The recruits froze every time a flare lit up the night sky, pressing their bodies flat to the ground under the razor wire.

As soon as the flare fizzled out, they kept on moving, inching through the sand. Drill instructors lobbed smoke grenades in their path, clouding the air, making it impossible to see. The razor wire caught and pulled on their Kevlar.

When Rainer Zarzour, 20, finally reached the end of the 30-foot stretch of razor wire, his drill instructor screamed at him to go back - another recruit was a few feet behind.
