DVIDS | MARINE CORPS BASE CAMP PENDLETON, Calif. -- As an instructor at the School of Infantry, a Marine is expected to be physically fit, mentally strong and have a vast amount of knowledge in their occupational field.
With one amputated leg, Gunnery Sgt. Gabriel Guest, the chief instructor
of the Advanced Machine Gunners course at Advanced Infantry Training
Battalion, School of Infantry - West, is no exception.
"When I joined the Marine Corps, I chose to join the infantry because I
like action and being in the thick of things, and because of the
challenge it presents," said Guest, a native of Spokane, Wash. "The
infantry is very dynamic because there are a lot of different aspects
you can master like weapons or tactics."
