  "Through these doors pass the world's finest infantry men.  
Out walks the world's deadliest weapon -- Marine Scout-Snipers."

The Marine Corps sniper is a Marine who has been carefully screened, selected, and has undergone comprehensive training in advanced infantry and marksmanship techniques. The sniper's training, combined with the inherent accuracy of his rifle, firmly establishes him as a valuable addition to the supporting arms available to the infantry commander.
The scout-sniper is a Marine highly skilled in field craft and marksmanship who delivers long range, precision fire at selected targets from concealed positions.
The primary mission of a sniper in combat is to support combat operations by delivering fire on selected targets from concealed positions. The sniper also has a secondary mission of gathering information for intelligence purposes.
The sniper is a highly specialized supporting arm and the sniper team (two men) should be employed independently, when at all possible, to take full advantage of their skills and to increase their probability of survival.

GONSALVES, HAROLD Medal of honor Citation

Rank and organization: Private First Class, U.S. Marine Corps Reserve. Born: 28 January 1926, Alameda, Calif. Accredited to: California. Citation: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as Acting Scout Sergeant with the 4th Battalion, 15th Marines, 6th Marine Division, during action against enemy Japanese forces on Okinawa Shima in the Ryukyu Chain, 15 April 1945. Undaunted by the powerfully organized opposition encountered on Motobu Peninsula during the fierce assault waged by his battalion against the Japanese stronghold at Mount Yaetake, Pfc. Gonsalves repeatedly braved the terrific enemy bombardment to aid his forward observation team in directing well-placed artillery fire. When his commanding officer determined to move into the front lines in order to register a more effective bombardment in the enemy's defensive position, he unhesitatingly advanced uphill with the officer and another Marine despite a slashing barrage of enemy mortar and rifle fire. As they reached the front and a Japanese grenade fell close within the group, instantly Pfc. Gonsalves dived on the deadly missile, absorbing the exploding charge in his own body and thereby protecting the others from serious and perhaps fatal wounds. Stouthearted and indomitable, Pfc. Gonsalves readily yielded his own chances of survival that his fellow marines might carry on the relentless battle against a fanatic enemy and his cool decision, prompt action and valiant spirit of self-sacrifice in the face of certain death reflect the highest credit upon himself and upon the U.S. Naval Service.

Medal of Honor, 1st. Lieutenant William Hawkins, 1943 (posthumous)

For valorous and gallant conduct above and beyond the call of duty as Commanding Officer of a Scout Sniper Platoon attached to the Second Marines, Second Marine Division, in action against Japanese-held Tarawa in the Gilbert Islands, November 20 and 21, 1943. The first to disembark from the jeep lighter, First lieutenant Hawkins unhesitatingly moved forward under heavy enemy fire at the end of the Betio pier, neutralizing emplacements in coverage of troops assaulting the main breach positions. Fearlessly leading his men on to join the forces fighting desperately to gain a beachhead, he repeatedly risked his life throughout the day and night to direct and lead attacks on pill boxes and installations with grenades and demolition. At dawn on the following day, First Lieutenant Hawkins returned to the dangerous mission of clearing the limited beachhead of japanese resistance, personally initiating an assault on a hostile fortified by five enemy machine guns and, crawling forward in the face of withering fire, boldly fired point-blank into the loopholes and completed the destruction with grenades. Refusing to withdraw after being seriously wounded in the chest during this skirmish, First Lieutenant Hawkins steadfastly carried the fight to the enemy, destroying three more pill boxes before he was caught in a burst of Japanese shell fire and mortally wounded. His relentless fighting spirit in the face of formidable opposition and his exceptionally daring tactics were an inspiration to his comrades during the most crucial phase of the battle and reflect the highest credit upon the United States Naval Service. He gallantly gave his life for his country.

Counter-Sniper/Gunfire Detection System. The counter-sniper system manufactured by the French company Metravib has potential to enhance the protection of U.S. forces deployed in the Balkans by providing location of sniper and harassing gunfire. This project is evaluating the French item with the objective of type classification and fielding to meet a U.S. Special Operations Command, Europe requirement.
