Lance Cpl. Michael Aceves, mid-right, a La Habara, Calif., native, and Lance Cpl. Chad Zibilich, far right, a New Orleans native, both aviation electronic technicians with Marine Aircraft Logistics Squadron 11, watch during a class aboard Marine Corps Air Station Miramar, Calif., March 8. Aceves and Zibilich, like most junior Marines, look to their sergeants for guidance both as Marines and people with differing personalities. It is a sergeant’s responsibility to learn these personalities and tailor his training to each individual so he can pass on as much of his knowledge as possible.
