United States Marine Corps Scout Sniper (MOS0317, formerly 8541) was 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. As of December 2023, Marine scout snipers (0317 MOS) have been reorganized as MOS 0322 Reconnaissance Sniper Marines, as part of a 26-Marine Scout Platoon.[2]
A USMC Scout Sniper Team was 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.
A Scout Sniper platoon was composed of 8–10 Scout Sniper teams, some of which are specially suited for night operations and fully capable of operating in almost complete darkness through use of night vision scopes and infraredlaser equipment. Typically, each Scout Sniper team has two members: one is the actual shooter, equipped with a long-range, specially-made sniper rifle, such as the M40, and also frequently issued an M9 9mm pistol as a defensive side arm; the other is the spotter, typically armed with an M4 carbine and uses a high-power spotting scope to spot targets and provide ballistic information for the shooter. The shooter/spotter relationship was not always set; some platoons established designated shooters, while others have team members taking turns doing the shooting/spotting. Within a platoon, there were four anti-materiel rifles chambered in .50 BMG designated the Special Application Scoped Rifle (SASR), such as the M82 or M107. These can be issued to a team as needed to give supported commanders the option of taking out heavy equipment or lightly armored vehicles. Scout Sniper teams trained to engage man-sized targets with the M40 out to 1000 yards, and can be effective at a range of up to 1.25 mi (2.01 km) with the M82, if the environment is right.
This image's publication, showing Scout Snipers posing with an flag in Afghanistan in 2010, triggered the controversy about the Scout Snipers' use of the symbol.
In February 2012, U.S. media reported that Marine scout snipers had been using the double Sig rune (ϟϟ, "SS") in its "Armanen" form () to symbolize their function since at least the 1980s.[4][5] The same stylized double rune was the symbol of the SS, the Nazi organization that was instrumental in conducting the Holocaust. Strong media criticism of this practice ensued. The Commandant of the Marine Corps gave orders to stop it, issued an apology, and ordered an investigation into the prevalence of this practice.[5]
A Marine official was quoted as saying that their leadership believed that the Marines did not understand the logo's significance.[5] The Military Religious Freedom Foundation, which had helped circulate an image of snipers posing with a blue "SS" flag, questioned this assumption, writing that the flag was sold by a website dedicated to German World War II and Nazi memorabilia.[6]
Despite the official prohibition, the New York Times reported in 2020 that the "SS" logo continues to be used by Marines, "much like a secret handshake".[7]
With the implementation of Force Design 2030, Marine scout snipers have been replaced with MOS 0322 Reconnaissance Sniper Marines, as part of a 26-Marine Scout Platoon.[2] The last 0317 class graduated December 15th, 2023.[8]
A Marine Corps Scout Sniper was a Marine highly skilled in fieldcraft and marksmanship who delivers long range precision fire, on select targets, from concealed positions in support of combat operations.
Support combat operations by delivering precision fire on selected targets.[9]
Establish concealed sniper/observation sites from which targets are analyzed, engaged, and information gathered.[10]
Use map and compass for day or night land navigation.[11]
Operate and maintain weapons and optical equipment employed by the Scout Sniper
Scout Snipers provided close reconnaissance and surveillance to the infantry battalion.[12] By doctrine, a Scout Sniper was a Marine highly skilled in field craft and marksmanship who delivers long range precision fire on selected targets from concealed positions in support of combat operations.
Scout Snipers in Marine infantry battalions fell under the Surveillance and Target Acquisition (STA) units initially, and subsequently to the infantry battalion's Scout Sniper Platoon (SSP), usually within the Headquarters and Service (H&S) Company or Weapons Company. Marine Scout Snipers were trained at one of the four school house locations.
The term "Scout Sniper" is only used officially by the Marine Corps, but it does not imply a differing mission from the U.S. Army Sniper. An Army Sniper's primary mission is to support combat operations by delivering precise long-range fire on selected targets. By this, the sniper creates casualties among enemy troops, slows enemy movement, frightens enemy soldiers, lowers morale, and adds confusion to their operations. The sniper's secondary mission is collecting and reporting battlefield information, Section 1.1 FM 23-10 Sniper Training.
The Marine Corps is unique in its consolidation of reconnaissance and sniper duties for a single Marine. Most other conventional armed forces, including the U.S. Army, separate the reconnaissance soldier or scout from the sniper. In the U.S. Army, the 19D MOS, "Cavalry Scout" is the primary special reconnaissance and surveillance soldier and the term "Infantry Scout" refers to a specially trained infantrymen that functions in a reconnaissance and surveillance capacity, while "Sniper" refers to a specially selected and trained soldier that primarily functions as a sniper.[13] Most military forces believe that the separation of reconnaissance and sniper capabilities allows for a higher degree of specialization.
U.S. Marine Corps Scout Sniper Course-East (SSC-East) logo
The Marine Scout Sniper Course qualified students as Marine Corps Scout Snipers. The graduation rate in 2017 was 44 percent.[14] There were three different school houses in the Marine Corps that offer the Scout Sniper Course.
In 2009, a major change in curriculum occurred with the Scout Sniper Basic Course and it was shortened from the traditional 10-week course to an 81⁄2 week course. This was done concurrently with the removal of the Advanced Course and the addition of the Team Leader Course of four weeks. This reduction of 11⁄2 weeks is because of the removal of the course's mission planning phase and the addition of this curriculum to the Team Leader Course. Missions are still conducted during the course's last week, but are now not a major part of curriculum.
In 2010, a new curriculum was introduced, with shooting as the course's primary focus and stalking a secondary focus. The new course was now 121⁄2 weeks long. With elimination of the advanced course, Scout Sniper Basic Course was re-designated as the "Scout Sniper Course". There were nine straight weeks of shooting qualifications, before the majority of field training.
These were the basic requirements that must be met in order to attend school. Units vary with indocs and pre-reqs.
Minimum Requirements: As per HQMC School Quota Message:
Criteria: 60 days prior to a class convening, the G-3 at each division will receive a message from HQMC stating the number of funded quotas given to each division, the gear list, report date, and criteria for attending.

It is highly recommended, but not required, for the student to have completed the following MCI courses: Land Navigation, Patrolling, Calling and Adjusting Supporting Arms, and Reconnaissance Marine. It is also recommended, but not required, that the student have conducted basic Scout Sniper field skills: stalks, concealment, field sketches, range cards, range estimations, and firing of the M40A1 rifle prior to attending the course. Students should also possess a high degree of maturity, equanimity, and common sense.
Swim Qual: 500 meter swim using side or breast stroke, 50 meter swim holding a weight out of water, tread water for 30 seconds holding a weight out of water, no signs of panic.
Phase 1: Marksmanship and Basic Fields Craft Phase
During this phase, Marines are trained in basic marksmanship on the Known Distance (KD) Range and also receive classes in basic skills such as camouflage, individual movement, weapons systems, observations, and field sketches.
Day one begins with in processing, which includes a PFT, gear check, and service record check for prerequisite compliance. Potential students must also pass day and night land navigation courses. After all students have been admitted to the course, classes and a general overview of the course are given.
KD range includes shooting at the 300, 500, 600, 700, 800, 900, and 1000 yard lines. Five rounds are fired at each yard line. During this phase of training, Marines must become experts at the fundamentals of marksmanship. They must also become experts at calling wind and weather. During this portion two students work together, one on the rifle and the other behind the spotting scope calling wind. If a student is not proficient at calling wind, they will cause their partner to fail, not themselves. After the first student fires his rounds, the two switch positions. After each yard line, the students must quickly throw on their packs and grab all their equipment and run to the next yard line. The course of fire for qualification is as follows:
300, 500, & 600: three stationary and two movers
700: three stationary and two stop and go movers
800: three stationary and two bobbers
900 & 1000: five stationary
Out of 35 rounds, 28 rounds must be in the black to qualify on the range.
After the range students head back to the schoolhouse and clean weapons. After this important task they immediately do a field sketch and observation exercises. Often a Kim's Game is conducted as well.
During an observation, students must use their M49 Spotting Scope and binoculars to find 10 hidden items in a specifically defined area. These observations can be done at short distances utilizing miniature items, or at long distances with full sized items. Observations are an essential skill that the sniper must learn to be effective. Furthermore, for the purposes of the course it is important to learn observation skills, particularly how to "Burn Through" bushes for the stalking phase. Learning this skill is imperative to being able to find the observation post from behind cover during stalking and is often the difference between a student passing or failing. An overall average of 70% must be obtained on observations to pass the course.
During a field sketch, students are given an hour and a specific area or building to sketch. The target must be drawn with as many details as possible. It must include information about its surroundings and target reference points on the sketch. Sketches are graded for neatness, correctness, details, and usable information. An overall average of 70% must be obtained on field sketches to pass the course.
Phase 2: Unknown Distance and Stalking
The UKD (Unknown Distance) and Stalking portion kicks off as soon as Phase 1 is completed. During this phase students will become experts at engaging targets at unknown distances by way of range estimation and range cards.
During the unknown distance phase students will run 100-pound steel targets out to ranges between 300 and 800 yards. There are 10 targets in each course of fire, and after each course of fire, the targets are rearranged.
A student has two attempts to hit each target, a first round impact is worth 10 points and a second is worth 8. An overall average of 80% must be obtained during the 3 weeks of UKD to pass the course. **Thereafter, the portion of the course with the highest attrition rate begins, stalking.
Stalking involves moving from a distance between 1200 and 800 yards to within 200 yards of an observation post (OP) undetected. After doing this, the student must set up a Final Firing Position (FFP) and fire two shots without being found by the OP within a time period of 3–4 hours.
After the first shot is fired, a walker (a neutral instructor who does not help students or the instructors in the OP) will get close to the sniper's position to make sure he can positively ID the OP. Positive ID is established by the observers holding up cards with 2-3 letters on them above their binoculars. The sniper must then correctly tell the walker what is written on them. After positive ID has been confirmed, the walker will move within 10 yards of the shooter and inform the OP that he is within 10. The OP will then attempt to walk the walker onto the sniper's position by way of movement commands. The OP must get the walker within 1 foot of the shooter. If the shooter cannot be found, the walker will tell the shooter to fire a second shot on his command. After the second shot has been fired, the OP will look for blast from the rifle or movement from the shooter. If the OP cannot find the shooter, then the walker will indicate the shooters position to the OP and check to make sure the shooter had the correct windage and elevation settings, along with correct position and stable shooting platform.
Grading is as follows for stalking:
0: Being out of bounds on the stalk lane, not freezing on the command freeze (when the OP believes they know the position of a student, they call freeze and all students on the stalk lane have to immediately freeze in whatever position they are in), poor FFP.
40: Caught out of range or fired out of range (not within 200 yards).
50: Caught within range.
60: 1 shot fired but, no positive ID, incorrect windage or elevation, unstable shooting platform.
70: 1 shot fired and positive ID, correct windage, elevation, shooting platform but OP walked onto shooter after first shot.
80: 2 shots fired and positive ID, correct windage, elevation, shooting platform but OP saw blast from shooter's position after second shot.
100: 2 shots fired and positive ID, correct windage, elevation, shooting platform and shooter was never found.
Students must obtain an overall average of 70% out of 10 stalks, with a minimum of two 100s and no more than a single zero in order to pass stalking.
Phase 3: Advanced Field Skills and Mission Employment
