United States Marine Corps Scout Sniper

United States Marine Corps Scout Sniper (MOS 0317, formerly 8541) is a secondary MOS (Military Occupational Specialty) designator of U.S. Marine Corps infantrymen and reconnaissance Marines that have graduated from a U.S. Marine Corps Scout Sniper School. Scout Snipers must earn the rank of Lance Corporal, be selected by their battalion to join the scout-sniper platoon, and complete an approved scout-sniper course in order to receive this designation.

A USMC Scout Sniper is a Marine, highly skilled in fieldcraft and marksmanship, who can deliver long-range precision fire on selected targets, from concealed positions.

A USMC Scout Sniper Team is a detachment of one or more sniper teams performing an assigned task of engaging selected targets, targets of opportunity, collecting and reporting information, or a combination of all, contributing to the accomplishment of the supported unit's mission.

Surveillance and Target Acquisition (STA) Platoons, very similar units, existed until shortly after the Gulf War. They consisted of Scout Snipers and Intelligence Marines.
