U.S. Marine Corps Sgt. Alfonso Torres, a senior drill

U.S. Marine Corps Sgt. Alfonso Torres, a senior drill instructor from 1st Battalion at Marine Corps Recruit Depot San Diego, instructs a Marine Corps Recruiting Substation Chandler enlistee to maintain his body in the push-up position during a physical training exercise at the Arrowhead Meadows Park in Chandler, Ariz., Jan. 23, 2013. Torres, a native of Merced, Calif., emphasized that the enlistees always work as a team. The enlistees are currently part of the delayed entry program and are awaiting their dates to ship to boot camp. The drill instructors are visiting the Phoenix region through Jan. 26 to provide enlistees and potential applicants a first-hand preview of what they may be able to expect once they step onto the yellow footprints.
