His team spotted by insurgents and forced to take cover in an abandoned compound, Marine sniper Joshua Moore went against his instinct when two grenades landed next to him, throwing one of them back at the enemy and holding off insurgent fire until help could arrive.
Moore, at the time a lance corporal, was later awarded the Navy Cross for his actions.
Moore was part of a scout sniper platoon during a mission in Marjah, Afghanistan, in March 2011, when insurgents targeted his team.
